The capacitance (C) of a reverse-biased abrupt Si p¹n junction has been measured as a function of the reverse bias voltage V, as listed in Table 6.7. The parasitic capacitance has been subtracted from the measurements so that C represents the depletion region capacitance. The pn junction cross-sectional area is 500 µm x 500 μm. By plot- ting 1/C² versus V,, obtain the built-in potential V, and the donor concentration N, in the n-region. What is No? Table 6.7 Capacitance at various values of reverse bias (V.)

Expert Answer:
Answer rating: 100% (QA)
we can plot 1C versus V The slope of this plot will give us the builtin potential Vbi and the yintercept will give us the donor concentration N Python ... View the full answer
