Assume NDNA1E15cm3 in two different slabs of semiconductor 1

Assume ND=NA=1E+15cm-3, in two different slabs of semiconductor (1 each doping type). Plot n/ND, p/NA at 100K, 300K, 500K for each wafer. What electron density did you get for T=100K? How much lower was it than Nd?

Solution

current density is total flow of charge per time over a crosssection area.

current density J=ne²T E/m
