  • Abstract
    Results of a theoretical analysis of avalanche breakdown in AlxGa1-xAs/GaAs heterojunctions are presented. All x values of AlxGa1-xAs in the heterojunctions were considered. The avalanche breakdown voltage was found to be maximum when the x of Alx Ga1-x As in heterojunctions was ~0.45. The maximum heterojunction breakdown voltage was ~400 V larger than that of a homojunction when donor and acceptor concentrations were 1014 cm-3. The results indicate that the use of a thyristor for pulsed power applications can improve the blocking capability of the device
