Q3. When Ge crystal is doped with phosphorus atoms, it becomes
Answer : Option A
Explaination / Solution:
Doping is the process of intentionally introducing impurities into an extremely pure (i.e., intrinsic) semiconductor in order to change its electrical properties. The impurities are dependent upon the type of semiconductor. Lightly and moderately doped semiconductors are referred to as extrinsic semiconductor. A semiconductor which is doped to such high levels that it acts more like a conductor than a semiconductor is called degenerate.
Dopant atoms can either be “donors” or “acceptors.” Donors increase the elctron concentration in the silicon, whereas acceptors increase the hole concentration.
When Germanium crystal is doped with phosphorus atoms, then it becomes N-type.
