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 ...

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 ...

Scientists move graphene closer to transistor applications

Scientists at the U.S. Department of Energy's Ames Laboratory were able to successfully manipulate the electronic structure of graphene, which may enable the fabrication of graphene transistors— faster and more reliable ...

The comeback kid—black phosphorus and its new potential

When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material for its potential as an ultra-thin ...
