Tiny antennas let long light waves see in infrared

(Phys.org) —University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum.

3-D view of 1-D nanostructures

Semiconductor gallium nitride nanowires show great promise in the next generation of nano- and optoelectronic systems. Recently, researchers at the McCormick School of Engineering have found new piezoelectric properties of ...

Modeling sunlight harvesting in nanostructures

To create the next generation of solar panels and other light-driven devices, scientists must model how complex interactions occur. Modeling across different scales, from individual atoms to very large systems with thousands ...

Cost-saving computer chips get smaller than ever

Not so long ago, a computer filled a whole room and radio receivers were as big as washing machines. In recent decades, electronic devices have shrunk considerably in size and this trend is expected to continue, leading to ...

Researchers use electron beams for chemical reactions

Electron microscopes use focussed electron beams to make extremely small objects visible. By combining the instrument with a gas-injection system material samples can be manipulated and surface structures measuring only nanometres ...
