-
The amount of photoelectric emission current depends on the frequency of incident light.
-
When a p-n junction is forward biased
-
The carriers of n channel JFET are
-
The depletion layer around p-n junction in JFET consists of
-
The mean free path of conduction electrons in copper is about 4 x 10-8 m. For a copper block, find the electric field which can give, on an average, 1 eV energy to a conduction electron
-
When a p-n-p transistor is properly biased to operate in active region the holes from emitter.
-
Assertion (A): Silicon is preferred over germanium in manufacture of semiconductor devices.
Reason (R): Forbidden gap in silicon is more than that in germanium.
-
Assertion (A): A decrease in temperature increases the reverse saturation current in a p-n diode.
Reason (R): When a diode is reverse biased surface leakage current flows.

At room temperature a semiconductor material is
