Abstract(in English) | In this paper, we reported the result of analysis of traps at the buffer in GaN HEMT by both transient response measurement and TCAD simulation. The two type devices which differ only in the concentration of Fe at GaN buffer layer was prepared, and the transient response from OFF state to ON state was measured at various temperature. Trap energy and capture cross-section at GaN buffer layer were extracted by analysis of time constant of traps. And, by using TCAD simulation and these trap parameters, the relationship with traps at GaN buffer layer and transient response was analyzed. In the result, it was found that transient current was increased because electrons which were captured in traps at GaN buffer at OFF state were emitted at ON state, and transient drain current was increased. |
