Briefly explain how intrinsic germanium can be turned into an
n-type germanium and a p-type
germanium by doping of selected impurity atoms. Sketch separate 2D
diagrams to help illustrate
the bonding/structures of extrinsic Ge in the locality of the
impurity atoms.
If an extrinsic germanium crystal has a hole concentration of
2.0x108 cm-3 at 300 K. Calculate
the electron concentration, n. Is the extrinsic Ge semiconductor an
n-type or p-type
semiconductor? Give your reason. (Given the intrinsic electron
concentration, ni...
