Recovery Performance of Ge-Doped Vertical GaN Schottky Barrier Diodes

Nanoscale Research Letters, 2019
Vertical GaN Schottky barrier diodes (SBDs) were fabricated on Ge-doped free-standing GaN substrates. The crystal quality of the SBDs was characterized by cathode luminescence measurement, and the dislocation density was determined to be ~ 1.3 × 106 cm ...
