How does the energy gap in an instrinsic semiconductor vary, when doped with a pentavalent impurity and a trivalent impurity. Draw their energy band diagrams.

How does the energy gap of an instrinsic semiconductor vary, when doped with a pentavalent impurity?

How does the energy gap of an intrinsic semiconductor vary, when doped with a trivalent impurity?

How does the forbidden energy gap of an intrinsic semiconductor vary with the increase in temperature

What is an extrinsic semiconductor? Discuss the working of the various types of extrinsic semiconductors with help of their energy band diagram.

An intrinsic semiconductor is doped with boron how will the energy gap change in semiconductor

An intrinsic semiconductor is doped with arsenic how will the energy gap change in semiconductor

Draw the "energy bands" diagram for a (i) pure semiconductor (ii) insulator. How does the energy band, foe a pure semiconductor, get affected when this semiconductor is doped with an acceptor impurity donor impurity? Hence discuss why the 'holes' and the 'electrons' respectively, become the 'majority charge carriers' in these two cases.
