Training light to cool the material it strikes

(—Light might one day be used to cool the materials through which it passes, instead of heating them, thanks to a breakthrough by engineers at Lehigh and Johns Hopkins Universities.

One-dimensional red phosphorous glows in unexpected ways

When electrons are confined into very small spaces, they can exhibit unusual electrical, optical and magnetic behavior. From confining electrons in two-dimensional atomic sheet graphene—a feat that won the Nobel Prize in ...

Probing semiconductor crystals with a sphere of light

Tohoku University researchers have developed a technique using a hollow sphere to measure the electronic and optical properties of large semiconducting crystals. The approach, published in the journal Applied Physics Express, ...
