Semiconductors -- role of displaced Silicon or Germanium
Revered Members,
When we dope a pure Germanium or Silicon with pentavalent impurity or trivalent impurity, the dopant replaces Silicon or Germanium and bonds with neighbouring Si or Ge atom. That is Dopant takes the centre position and bonds with 4 neighbouring atoms.
Now where do that replaced Si or Ge go in the crystal?
