Question

How can the conductivity of metalloids be increased?

Answer 1

Answer:

The electrical conductivity of a semiconductor increases with increase in temperature because with increase in temperature the electrons overcome the energy barrier between the valence band and the conduction band easily. For semiconductor, it increases as promotion of electrons to conduction band from valence band.

Answer 2

The electrical conductivity of a semiconductor increases with increase in temperature because with increase in temperature the electrons overcome the energy barrier between the valence band and the conduction band easily. For semiconductor, it increases as promotion of electrons to conduction band from valence band.
