Question

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

Answer 1

$\rule{200}{2}$

$\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}$

The conductivity in an intrinsic semiconductor is due to the thermal motion of bound electrons. But extrinsic semiconductor contains more number of free electrons in case of n-type (and free holes in p-type) due to which the current flows. Thus conductivity of intrinsic semiconductor is more than that of extrinsic.

Answer 2

Answer:

The conductivity in an intrinsic semiconductor is due to the thermal motion of bound electrons. But extrinsic semiconductor contains more number of free electrons in case of n-type (and free holes in p-type) due to which the current flows. Thus conductivity of intrinsic semiconductor is more than that of extrinsic.
