摘要

The I_c, I_B-Gummel plots (1) are extensively used (2-7) for the characterization of the heterojunction bipolar transistors and monitoring of process parameters and device reliability. Usually, the collector current is written asrnI_C=I_0exp{(qV_(BE)/(nkT)} [1]rnfor junction voltages V_(Be) ≥ 0.2 V and V_(Bc) = 0 V. The saturation current I_0 and ideality factor n are not dependent on emitter-base voltage V_(BE).rnIn the thermionic theory given by Grinberg et al. (8), n gets the value
