The mechanisms and the timescale of charge separation in photovoltaics have been the subject of controversial scientific debate for many years. Scientists ave now been able to dissect the process in detail.
Empa-Forschende entwickelten ein Herstellungsverfahren fuer Nano-Cellulosepulver, aus dem sich Polymerverbundwerkstoffe herstellen lassen, die beispielsweise als Leichtbauwerkstoff im Automobilbau oder als Membran- oder Filtermaterial in der Biomedizin Verwendung finden koennten.
Many illnesses are now being linked to particular patterns of mutations in an individual's DNA. However, the search for these patterns, known as haplotypes, is generally a slow and painstaking process. Yongyong Shi and colleagues from Shanghai Jiao Tong University in China have now shown how gold nanoparticles can be used to turn haplotyping into a high-throughput process.
The ENIAC Joint Undertaking invited the European R+D actors in nanoelectronics to express their interest to coordinate Key Enabling Technologies "Pilot Line" projects underpinning up to 1 billion euros of private and public investments in the next 2 years.
KIT researchers have developed a new concept for rechargeable batteries. Based on a fluoride shuttle -- the transfer of fluoride anions between the electrodes -- it promises to enhance the storage capacity reached by lithium-ion batteries by several factors.
For ion implantation, that is 'hammering' ions into the surface layer of the material, conventional ion accelerators are commonly used. Laser ion sources are much simpler, cheaper and more universal. However, they emit wide energy ions usually accompanied by some admixtures. In the Institute of Plasma Physics and Laser Microfusion in Warsaw a unique laser ion source has been built which is equipped with a special system for accelerating ions to a chosen energy and for eliminating admixtures.
CSTIC is the largest annual industrial semiconductor technology conference in China. It is organized by SEMI and ECS, co-organized by China's High-Tech Expert Committee (CHTEC) and co-sponsored by IEEE, MRS and China Electronics Materials Industry Association.
Imec researchers, in collaboration with Tokyo Electron, have successfully integrated and characterized carbon nanotubes (CNT) into 150nm contact holes with a TiN underlayer and a Cu single damascene top contact module. The process steps are CMOS-compatible and the platform is designed for fast and automatic electrical testing and for benchmarking different CNT recipes and process conditions.
Imec engineers have, for the first time, demonstrated the fabrication of extremely small sealed cavities (less than one picoliter in volume), fabricated directly on 200mm silicon wafers. The crucial process step is the production of freestanding thin membranes of nanoporous anodic alumina.
Imec in collaboration with Lam Research presents a new method for the quantitative evaluation of wafer drying techniques. The method uses Si nano-pillar test structures in combination with top-down scanning electron microscopy (TD-SEM) inspection.
