Abstract :
The effect of heavy doping on the capacitance-voltage relation of abrupt and linearly-graded p-n junctions is studied by computer simulations. An estimate of bandgap narrowing in compensated silicon is given for linearly-graded junctions. Capacitance-voltage curves of abrupt p-n GaAs junctions grown by MBE are investigated and compared to the theoretical curves
