Answer Posted / rini paul
For a pure Semiconductor at absolute zero temperature,the valance band is usually full & they are maybe no electron in the conduction band.It's difficult to provide additional energy required for lifting electron from valance band to conduction band by applying electric field.Hence, the conductivity for a pure semiconductor at absolute zero temperature is zero & it behaves like insulator.
