Nano and Giga Challenges in Electronics Photonics and Renewable Energy (NGC2011) Moscow-Zelenograd, Russia, September 12-16, 2011

This special issue of Nanoscale Research Letters is a collection of selected papers presented at the Nano and Giga Challenges in Electronics, Photonics and Renewable Energy (NGC2011) conference in Moscow and Zeleno grad which addresses both theoretical and experimental achievements and provide a stimulating outlook for technological developments in these highly topical fields of research. Informational (electronics and photonics) and renewable energy (solar systems, fuel cells and batteries) technologies have reached a new stage in their development – engineering limits in cost effective improvement of current technological approaches. The latest miniaturization of electronic devices is approaching atomic dimensions, interconnect bottlenecks are limiting circuit speeds, new materials are being introduced into microelectronics manufactured at an unprecedented rate, and alternative technologies to mainstream CMOS are being considered. The low cost of natural energy sources and ignorance of the limits and environmental impact from use of natural carbon based fuels have been long standing economic barriers to the development of alternative and more efficient solar systems, fuel cells and batteries. Nanotechnology is widely accepted as a source of potential solutions in securing future progress in information and energy technologies. Academic and industrial researchers participated at NGC2011 conference presented tutorial, expository and original research papers dedicated to solving scientific and technological problems in electronics, photonics and renewable energy such as atomic scale materials design, bioand molecular electronics, high frequency electronics, fabrication of nanodevices, magnetic materials and spintronics, materials and processes for integrated and subwave
