5.1 <strong>Carrier</strong> Drift<br />
Drift current density<br />
Consider a positively charged hole,<br />
When electric field, E, is applied, the hole accelerates<br />
F = mp<br />
a =<br />

m*p; effective mass of hole, a; acceleration, e; electronic charge<br />
However, hole collides with ionized impurity atoms and with thermally vibrating<br />
