This Perspective surveys the role of thermal nonlinearity in figures of merit through a multiscale physical understanding to advance heat harvesting technologies beyond linear processes, focusing ...

The density of states is an important quantity for a quantum material. Here, we demonstrate how singularities in the density of states can be characterized and engineered, combining the ...

“The back-side of the device was polished to a 45-degree chamfer in order to refract the intraband beam which was incident on the back of the device,” said the researchers. The scientists ...
