... The difference between semiconductors and insulators is that in semiconductors electrons can reach the conduction band at ordinary temperatures, where in insulators they cannot. The probability that an electron reaches the conduction band is about exp(-Eg/2kT) where Eg is the band gap. If this p ...

Find the resistivity at 300 K for a Si sample doped with Phosphorus (P): 1.0x1014 cm-3 Arsenic (As): 8.5x1012 cm-3 Boron (B): 1.2x1013 cm-3 The electron mobility of Si is µn=1500 cm2/Vs and the hole mobility µp=500 cm2/Vs. Hint: the dopants can be either acceptors or donors depending on the group ...

... current does not change. In this case, drift current is limited not by how fast carriers are swept across the depletion layer, but rather how often. In equilibrium the drift current is limited by the number of minority carriers which are thermally generated within a diffusion length of the junction. ...
