AlGaN/GaN HEMT is a promising device for detection of breast cancer, which operates on the principle of specific binding of c-erbB-2 protein through bio-functionalized layers of Gold and Thioglycolic acid applied on the gate region. In this paper, a simulation based study of the effect of various sensing parameters on device sensitivity is performed using nextnano3 simulation tool. These parameters include interface charge densities, thioglycolic acid concentration and c-erbB-2 concentration. The simulated device exhibits high current sensitivity of the order of 100 μA/mm for 20 μg/ml change in c-erbB-2 concentration in saliva, under practical environmental conditions.
