A defect found in barium stannate (BaSnO3) perovskite crystals could one day lead to a new type of transparent conductive film, according to scientists at the University of Minnesota. The defect is a one-dimensional (line) defect that runs through single crystals of the material aligned with one of the crystal axis. “The conductive nature and ...

Researchers at Nagoya Institute of Technology have found a way to create a 3D map of carriers inside silicon carbide power transistors without sawing them up, proposing the system as a way of improving SiC bipolar devices. The technique, which works down to 250μm and has ~10μm resolution, is ‘time-resolved free carrier absorption with inter-sectional lights ...
