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 … NettetFor a linearly graded junction, tables of bounds are given which nowhere differ by as much as 1 per cent, and which effectively bridge the gap between the space-charge case and the neutral case. The computer solutions are used to calculate the voltage dependence of the stored charge (low-frequency ac capacitance) of a graded junction …
