Does doping always increase the conductivity of a semiconductor?
The conductivity of a semiconductor is given as (if extrinsic):
\$\sigma = qnu_e + qpu_h\$
where \$\sigma\$ is the conductivity, \$u_e\$ and \$u_h\$ are the electron and hole mobilities.
But does ...

Relation between drift velocity & conductivity of a doped semiconductor
Here is the problem, and I am stuck.
When an electric field with strength \$1 \times 10^3 \text{V/cm}\$ is
applied to a p-type uncompensated Si sample at room temperature, the
electron drift ...
