Abstract
AlGaN/6H-SiC heterojunction bipolar transistors (HBTs) were fabricated, and the device performance as well as the electrical properties of the n-AlGaN/p-SiC heterojunction were studied by temperature dependent current-voltage characterization. Current gain β=IC/IB calculated from I-V characteristics varied from sample to sample in the range of 75-100. A barrier height of 1.1 eV is derived from the Arrhenius plot and its origin is discussed.
