pseudo-vertical gan p-n diodes
In this study, we introduce a thick GaN-on-Si pseudo-vertical p-n diode grown with Selective Area Growth (SAG). For the first time, we measured temperature-dependent current-voltage characteristics in the range of 303 to 413 K to explore the origin of leakage conduction in a p-n diode produced via SAG. Two conduction mechanismd are identified as Frenkel-Poole Emission and Variable Range Hopping . Additionally, employed TCAD simulations and Lock-in Thermography to investigate and pinpoint the leakage current.
