Chapter 1: Semiconductor material
Semiconductor is a material that has a conductivity level somewhere between that of -----------
and that of -----------.
2 types of semiconductor that commonly used in industries are ---------- and------------. Between
these two, --------------is widely used. This is because of its low cost, stable at high temperature
and low reverse saturation current.
Electron at outermost orbit of atom is called-----------
Si and Ge are element from which group?-------------
