Introducing a vertical arrangement of n and p layers into the drift layer of semiconductors to enable bipolar operation is a way around the 'unipolar limit' problem in semiconductors. But defect ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Silicon carbide (SiC) unipolar semiconductors are in wide commercial use, but their operations are limited by a trade-off relationship between breakdown voltage and specific resistance of the drift ...
