Our economy is more and more driven by content and leveraged by high performance, cost-effective hardware and storage. Today people collect create and share more and more digital information. Very high-definition video and social networking will fuel the storage demand further. Optical memories are one of the most successful data storage technologies, economically and technically. In 2007, around 700 million optical disc drives and 36 billion discs have been manufactured. Optical memories ideally combine media removability, media longevity, random access, lowest costs and are today the dominant consumer storage format for content distribution and archival. However, the conventional bit recording technology (like BD and HD-DVD) has been pushed already close to its practical limits. To further increase the effective data density several technologies exist: multi-layer, optical super resolution, optical near-field technologies, Super-RENS (Super Resolution Near-field Structure) and advanced channel modulation/coding. The next generation optical storage systems for practical application in 3\ years from today will likely be provided by a mixture of these evolving and future technologies. The objective of this project is to investigate the above mentioned technologies and their combination. Specific key components such as -SIL, laser spot confinement optics, cross talk cancellation, advanced methods for modulation and coding and stampers and layer structures for read-only and rewritable discs will be developed. The expected outcome is the specification and demonstration of an optical storage system with a capacity of 200 to 400 GByte on a 12 cm disc. This will be the technological basis for a new-generation optical storage format required consumer applications. The scope of this project fits to the call objective 3.6 Micro-/Nanosystems with expected outcomes for high density mass storage for next generation smart systems.

The ambition of PhotoNvoltaics is to enable the development of a new and disruptive solar cell generation resulting from the marriage of crystalline-silicon photovoltaics (PV) with advanced light-trapping schemes from the field of nanophotonics. These two technologies will be allied through a third one, nanoimprint, an emerging lithography technique from the field of microelectronics. The outcome of this alliance will be a nano-textured thin-film crystalline silicon (c-Si) cell featuring a drastic reduction in silicon consumption and a greater cell and module process simplicity. It will thus ally the sustainability and efficiency of crystalline silicon PV with the simplicity and low cost of the current thin-film solar cells. The challenge behind PhotoNvoltaics lies behind the successful identification and integration of these nano-textures into thin c-Si-based cells, which aim is a record boost of the light-collection efficiency of these cells, without harming their charge-collection efficiency. The goals of this project are scientific and technological. The scientific goal is two-fold: (1) to demonstrate that the so-called Yablonovitch limit of light trapping can be overcome, with specific nanoscale surface structures, periodic, random or pseudo-periodic, and (2) to answer the old question whether random or periodic patterns are best. The technological goal is also two-fold: (1) to fabricate thin c-Si solar cells with the highest current enhancement ever reached and (2) to demonstrate the up-scalability of this concept by fabricating patterns over industrially relevant areas. To reach these goals, PhotoNvoltaics will gather seven partners, expert in all the required fields to model and identify the optimal structures, fabricate them with a large span of techniques, integrate them into solar cells and, finally, assess the conditions of transferability of these novel concepts, that bring nanophotonics into PV, further towards industry.

Carbohydrate biomass constitutes an abundant and renewable resource that is attracting growing interest as a biomaterial. Convincingly the use of different natural elementary bricks, from oligosaccharides to fibers found in biomass, when mimicking self-assembly as Nature does, is a promising field towards innovative nanostructured biomaterials, leading to eco-friendly manufacturing processes of various devices. Indeed, the self-assembly at the nanoscale level of plant-based materials, via an elegant bottom-up approach, allows reaching very high-resolution patterning (sub-10nm) never attained to date by petroleum-based molecules, thus providing them with novel properties. GREENANOFILMS aims to use carbohydrates as elementary bricks (glycopolymers, cellulose nanocrystals and nanofibers) for the conception of ultra-high resolution nanostructured technical films to be used in various markets, from large volume sectors, such as (i) high-added value transparent flexible substrate for printed electronic applications, (ii) thin films for high-efficiency organic photovoltaics, to growing markets, such as (iii) next generation nanolithography and (iv) high-sensitivity SERS biosensors. GREENANOFILMS main impacts are the implementation of a new generation of ultra-nanostructured carbohydrate-materials that will play a prominent role in the achievement of the sustainability improvement of various opto- and bio-electronic sectors. A network of industrial end-user leaders is integrated in the project to facilitate the innovator-to-market perspective. The prospective environmental impacts and benefits of new green processes, eco-efficient nanomaterials and nanoproducts will be quantified with Life Cycle Assessment, risk assessment and validation of the industrial feasibility, including economic evaluation of the products. The results will be disseminated to the European smart paper, printed electronic, photovoltaic, display, security and health communities.

Solid state light sources based on compound semiconductors are opening a new era in general lighting and will contribute significantly to a sustainable energy saving. For a successful and broad penetration of LEDs into the general lighting market two key factors are required: high efficiency and low cost. Two new disruptive technologies based on nanostructured semiconductors are proposed to address these key factors. A novel epitaxial growth technique based on nanorod coalescence will be explored to realize ultra-low defect density templates which will enable strain-relieved growth of LEDs and thus achieve higher efficiency. The second highly innovative approach is the growth of directly emitting Gallium nitride based nanorod structures. These structures are expected to produce exceptionally high efficiency devices covering the whole visible spectrum and even phosphor-free white LEDs. Significantly, our new nanostructured compound semiconductor based technology will enable LED growth on low-cost and large-area substrates (e.g., Silicon) as wafer bowing will be eliminated and thus lead to a dramatic reduction in production costs. The main objectives over the three years are: Profound understanding of the growth mechanisms and properties of nanorod systems New materials and process technologies (wafer-scale nanoimprinting, dry etching, device processing) for LEDs based on nanostructured templates and nanorod-LEDs Demonstrators: -Phosphor-converted white LEDs based on nanostructured sapphire templates (efficacy 150 lm/W @ 350 mA) and Silicon templates (efficacy 100 lm/W @ 350 mA) -Blue, green, yellow and red emitting Nano-LEDs (external quantum efficiency 10%) -Novel phosphor-free white-emitting Nano-LEDs (external quantum efficiency 2%) Realising the objectives of SMASH will start a new generation of affordable, energy-efficient solid state light sources for the general lighting market and will push the LED lamp and luminaire business in Europe.

The TERAMAGSTOR project aims through a systems approach at designing, fabricating and testing future perpendicular magnetic storage media with areal density larger than 1 Tbit/in2. To overcome the technological barriers limiting the areal density, the proposed approaches address both key media feasibility issues (thermal stability, writability, signal to noise ratio) and low cost, high throughput media fabrication methods. The approaches are based on the development of advanced film media (exchange spring and percolated media), nanolithographically patterned and nanoparticles patterned by templates through an integration of professional skills (chemists, physicists, engineers, materials scientists).The activity will cover media preparation and characterisation, magnetization reversal processes, numerical micromagnetic simulations, measurements of write/read recording characteristics and signal modelling and processing. The innovation and the ultimate goal is to produce the first EU 1.8 /2.5\nHD with density in excess of 1 Tbit/in2 , through synergistic approach using EU groups and the exploitation by the two IND .It is based on previous work by most of the consortium members, which led to a record of 220 Gbits/in2 (Descartes prize 2005). The expected impact of TERAMAGSTOR is to open the way to a new generation of ultrahigh density magnetic recording media, through a basic investigation of magnetic phenomena in the nanoregime and the development of new fabrication processes, favouring the EU technological progress and competitiveness in the key technological area of magnetic storage and in general to the ICT business.
