Doping investigation of structured GaN devices by highly lateral resolved TOF-SIMS
The measurement of doping concentrations is a fundamental need for the development and processing of power electronic devices like normally-off semi-vertical GaN trench MOSFETs. We employed highly laterally resolved TOF-SIMS to evaluate the doping levels of the n- and p- doped layers close to the ga...
