The shape of things to come for quantum materials?

For the first time, researchers isolated and characterized atomically thin 2-D crystals of pentagons bonded together in palladium diselenide (PdSe2). The research confirmed predictions that the puckered structure would be ...

Proper breeding ground for germanene

Germanene is a one atom thick sheet of germanium, in a honeycomb structure. It has clear similarities with graphene, the material that induced massive research activity worldwide, especially after 2010's Nobel Prize.

Innovation is step toward digital graphene transistors

Researchers are making progress in creating digital transistors using a material called graphene, potentially sidestepping an obstacle thought to dramatically limit the material's use in computers and consumer electronics.

New alloys key to efficient energy and lighting

A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight, and to better light-emitting diodes (LEDs) that could replace ...

Slow 'hot electrons' could improve solar cell efficiency

Photons with energy higher than the band gap of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy in respect to the band gap is lost very fast, as it is converted into heat and ...

Manipulating wrinkles could lead to graphene semiconductors

Graphene has generally been described as a two-dimensional structure—a single sheet of carbon atoms arranged in a regular structure—but the reality is not so simple. In reality, graphene can form wrinkles which make the ...
