p-GaN field plate for low leakage current in lateral GaN Schottky barrier diodes

Elison de Nazareth Matioli, Luca Nela, Catherine Erine

High-voltage gallium nitride Schottky barrier diodes (SBDs) suffer from large off-state leakage current, which further degrades during operation at high temperatures and limits the device blocking capabilities. The key to achieving low off-state leakage is ...
