Abstract: 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 3 N 4 passivation layer, is mainly utilized to model the device. The simulation of Schottky diode has been performed in the TCAD tool and I-V curves are generated. From the I-V curves, 54% response has been recorded in presence of 500 ppm gas and at biasing voltage of 0.95 Volts.
