Nano Optoelectronic Sensors and Devices

Nanophotonics has emerged as a major technology and applications domain, exploiting the interaction of light-emitting and light-sensing nanostructured materials. These devices are lightweight, highly efficient, low on power consumption, and are cost effective to produce. The authors of this book have been involved in pioneering work in manufacturing photonic devices from carbon nanotube (CNT) nanowires and provide a series of practical guidelines for their design and manufacture, using processes such as nano-robotic manipulation and assembly methods. They also introduce the design and operational principles of opto-electrical sensing devices at the nano scale. Thermal annealing and packaging processes are also covered, as key elements in a scalable manufacturing process. Examples of applications of different nanowire based photonic devices are presented. These include applications in the fields of electronics (e.g. FET, CNT Schotty diode) and solar energy. read more...

Nanostructured metal coatings let the light through for electrical devices

CHAMPAIGN, Ill. – Light and electricity dance a complicated tango in devices like LEDs, solar cells and sensors. A new anti-reflection coating developed by engineers at the University of Illinois at Urbana Champaign, in collaboration with researchers at the University of Massachusetts at Lowell, lets light through without hampering the flow of electricity, a step that could increase efficiency in such devices. read more...

Nanocavity Paves Way for Thinner Solar Panels, Optoelectronic Devices

Researchers have been looking for ways to improve energy absorption and transfer to improve photovoltaics and optoelectronics. We told you recently how scientists invented new energy-carrying particles to this end, and now researchers at the University of Buffalo (UB) are experimenting with nanotechnology to improve the design of ultrathin solar panels, video cameras, and other optoelectronic devices. read more...
