Change of linearity and gain with different drain and gate bias has been studied for AlGaN/GaN HEMT on Sapphire substrate. While linearity increases with higher drain bias, maximum gain of the device decreases. Generation of more phonon and its related scattering of electrons decrease the mobility of carries. It further minimizes the drain current at high(More)
Potential application of amorphous silicon nitride (a-Si3N4)/silicon oxy-nitride (SiON) film has been demonstrated as resistive non-volatile memory (NVM) device by studying the Al/Si3N4/SiON/p-Si metal–insulator–semiconductor (MIS) structure. The existence of several deep trap states was revealed by the photoluminescence characterizations. The bipolar(More)
A physics-based analytical modeling for the gas sensor application of AlGaN/GaN heterostructure Schottky diode has been investigated for high linearity and sensitivity of the device. The heterointerface and surface properties are exploited here. The dependency of 2DEG on the surface charge, which is dependent on the Si<sub>3</sub>N<sub>4</sub> passivation(More)
