In this work, the comprehensive study of an interesting Pd/AlGaAs pseudomorphic high electron mobility transistor (pHEMT) based hydrogen sensor is implemented. The theoretical analysis and simulation are made by using a two-dimensional simulator Medici. In addition, a practical device is fabricated successfully. Based on the variations of the catalytic metal work function, the DC characteristics of experimental and simulated results are compared and studied.
