Assertion: The conductivity of an intrinsic semiconductor depends on its temperature. Reason The conductivity of an intrinsic semiconductor is slightly higher than that of a lightly doped p-type semiconductor.

The electrical conductivity of intrinsic and p-type semiconductor increases with increase in

When on impurity is doped into an intrinsic semiconductor, the conductivity of the semiconductor

A pure semiconductor germanium or silicon, free of every impurity is called intrinsic semiconductor. A room temperature, a pure semiconductor has a very small number of current carriers (electrons and holes). Hence, its conductivity is low. When the impurity atoms of valence five or three are doped in a pure semiconductor, we get repectively n-type ot p-type extrinsic semiconductor. In case of a doped semiconductor. n_(e)n_(h)=n_(i)^(2) , where n_(e) and n_(h) are the number density of electrons and holes respectively and n_(i) is the number density of intrinsic charge carriers in a pure semiconductor. The conductivity of extrinsic semiconductor is much higher than that of intrinsic semiconductor. (i) Name two materials to be doped in pure semiconductor of silicon to get p-type semiconductor n-type semiconductor. (ii) What do you learn from the above study?

When an impurity is doped into an intrinsuc semiconductor,the conductivity of the semiconductor

Statement 1: Conductivity of semiconductor increases with increase in temperature. Statement 2: Forbidden energy gap is highest for semiconductors.

Why is the conductivity of n-type semiconductor greater than that of the p-type semiconductor even when both of these have the same level of doping?

Statement-1 : When the temperature of a semiconductor is increased, then its resistance decreases. Statement-2 : The energy gap between conduction band and valence band is very small for semiconductor.
