The phenomenon of cathodoluminescence gave geologists an easy way to identify quartz and other minerals in rock samples. Cathodoluminescence allows a piece of quartz to glow icy blue when put under an electron scanning microscope. Now, scientists have used this phenomenon to probe into nanostructures.

“Silicon Nanophotonics” Integrates Optical Components with Electrical Circuits

cross-section-nanophotonic-silicon-chip

IBM announced an advance in the ability to use light instead of electrical signals for information transmission in future computing applications. “Silicon nanophotonics” allows the integration of different optical components side-by-side with electrical circuits on a single silicon chip, using sub-100nm semiconductor technology.

New 3D Form of Graphene May Lead to Flexible Electronics

graphene-monash-elastic

Graphene can support 50,000 times its own weight and can spring back into shape after being compressed by up to 80%. Graphene also has a much lower density than comparable metal-based materials. A new super-elastic, three-dimensional form of graphene can conduct electricity, and will probably pave the way for flexible electronics.
