Working with ultrathin membranes of the semiconductor indium arsenide, a team of researchers at the Berkeley Lab has discovered a quantum unit of photon absorption that should be general to all 2D semiconductors, including compound semiconductors of the III-V family that are favored for solar films and optoelectronic devices.

As part of an international team of researchers, scientists at the Helmholtz Center Berlin have observed the switching mechanism from a non-conducting to a conducting state in iron oxide (specifically, magnetite) with previously unrealized precision. This switching mechanism, which in oxides proceeds in two consecutive steps, is thousands of times faster than it is in current transistors.
