Power stations driven by light
Tue, 15 Jan 2019 13:28:56 EST
The smallest building blocks within the power stations of organisms which get their energy directly from the sun are basically miniature reactors surrounded by collectors which capture photons and forward them to the center. The close correlation between structure and interaction of the components boosts productivity, a strategy which researchers are using for increasing the efficiency of solar technology.
A new way to measure solar panel degradation
Thu, 10 Jan 2019 14:17:35 EST

Assessing the promise of gallium oxide as an ultrawide bandgap semiconductor
Tue, 18 Dec 2018 11:51:59 EST
In microelectronic devices, the bandgap is a major factor determining the electrical conductivity of the underlying materials, and a more recent class of semiconductors with ultrawide bandgaps are capable of operating at much higher temperatures and powers than conventional small-bandgap silicon-based chips. Researchers now provide a detailed perspective on the properties, capabilities, current limitations and future developments for one of the most promising UWB compounds, gallium oxide.
