摘要
Heterojunction bipolar transistor (HBTs) based on Al0.15Ga0.85 N/6H-SiC heterojunction was fabricated. Room-temperature current-voltage (I-V) characteristics of n-Al0.15Ga0.85 N/p-6H-SiC emitter-base heterojunction exhibited good rectifying behavior with a forward current 5 x 10(-2) A and reverse current 3 x 10(-9) A at 10 V and -10 V, respectively. Analysis of the temperature dependent I-V characteristics of this heterojunction revealed a barrier height of 1.1 eV. The fabricated n-Al0.15Ga0.85 N/p-SiC/n-SiC bipolar transistor did not exhibit common-emitter operation, however, common-base operation was observed with current gain beta = IC/IB ranging in 75-100.
