2D Janus materials could harvest abundant hydrogen fuel

Several studies have predicted that the water splitting reaction could be catalyzed by certain groups of 2D materials—each measuring just a few atoms thick. One particularly promising group are named 2D Janus materials, ...

Explained: Bandgap

Why do some materials work well for making solar cells or light-emitting diodes (LEDs), while other materials don't? One key factor is having the right bandgap.

Mismatched alloys are a good match for thermoelectics

(PhysOrg.com) -- Using the supercomputers at NERSC, Berkeley Lab researchers demonstrated that the semiconductors known as highly mismatched alloys (HMAs) hold great promise for the future development of high performance ...

Scientists demonstrate tunable, atomically thin semiconductors

To tune the band gap, a key parameter in controlling the electrical conductivity and optical properties of semiconductors, researchers typically engineer alloys, a process in which two or more materials are combined to achieve ...

A new approach to building efficient thermoelectric nanomaterials

By doping a thermoelectric material with minute amounts of sulfur, a team of researchers has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture. ...
