Reducing leakage current in GaN-Schottky diodes by suppressing hollow core nanopipes

The nanopipes in GaN films grown on sapphire substrates using metal-organic chemical vapor deposition were identified as leakage-related defects through investigations by PeakForce tunneling atomic force microscopy. An insertion layer of n-Al0.03Ga0.97N can prevent nanopipes from extending, thereby...
