The type of semiconductor formed when silicon combine with the given set of elements has to be determined. Concept Introduction: Semiconductors are substances that conduct electricity either by addition of an impurity or by the effects of temperature on it.

The addition of an element having either more or less number of valence electrons than the natural semiconductor decides the combination as the following two types of semiconductor. n - type semiconductor: (conduction is due to movement of extra electrons) The element added will have more valence electron than the natural semiconductor. Therefore, the extra electron from the added element resides in conduction band and increase the conductivity.
