NettetThis paper presents a numerical analysis of the mechanisms of operation within a linearly-graded p-n junction. Considered in this analysis are three important modes of junction operation: equilibrium, forward bias, and reverse bias in the collector junction. In addition, calculations of electrical space-charge layer capacitance are presented for the forward … Nettet6 3. Analysis and results 3.1. Capacitance-voltage characteristics analysis The C-V curves were measured as a function of temperature and bias voltage (V). In following we analyze these C(V) data in the framework of the standard theory of C-V [6]. The linearity of the C-3 vs. V curves (see Fig. 2 for TDJ and Figs. 3 a, b for IJ) clearly indicates that the …
