Making dark semiconductors shine

Whether or not a solid can emit light, for instance as a light-emitting diode (LED), depends on the energy levels of the electrons in its crystalline lattice. An international team of researchers led by University of Oldenburg ...

Atomically thin semiconductors for nanophotonics

Atomically thin semiconductors such as molybdenum disulfide and tungsten disulfide are promising materials for nanoscale photonic devices. These approximately 2D semiconductors support so-called excitons, which are bound ...

Superhard material synthesis made cheaper

Skoltech researchers and their colleagues from Tomsk Polytechnic University have proposed an efficient and inexpensive way to synthesize superhard tungsten boride, used in drilling and other industrial technologies. The research ...

New electronic paper displays brilliant colours

Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be a reality. ...

Probing the dynamics of photoemission

Almost a century ago, Albert Einstein received the Nobel Prize for Physics for his explanation of the photoelectric effect. Published in 1905, Einstein's theory incorporated the idea that light is made up of particles called ...
