Abstract(in English) | The current transport characteristics of the quasi-Al_xGa_<1-x>N/SiC Heterojunction Bipolar Transistors (HBTs) with various band discontinuities were investigated in the low current range by means of Gummel plot. In the low current range, the base currents of the HBTs were dominated by recombination currents and the amount of recombination among the HBTs were different. The collector current characteristics of the HBTs were almost the same in spite of the various band discontinuities and the ideality factors n were 1.0. The collector currents were dominated by the diffusion process in the base region and electrons were injected from the AlGaN emitter without any additional voltage drops in the low current range. |
