New paper shows how atomic segregation affects Schottky barrier transport
Controlling oxide-silicon semiconductor heterojunctions is a perpetual challenge in engineering electronic devices, including field-effect transistors and solar cells. We used advanced microscopy to perform an atom-by-atom deconstruction of the interface…
