Semiconductor E...

The Fermi level of an intrinsic semiconductor is pinned at the centre of the band gap. The probability of occupation of the highest electron state in valence band at room temperature, will be

There are two holes O1 and O2 in a tank of height H.The water emerging from O1 and O2 strikes the ground at the same points, as shown in fig.then.

The logic circuit shown in figure has the input wavefrom A and B as shown pick out from figure

Figure shows the particle realization of a logic gate. Identify the logic gate

The adjoining logic symbol is equivalent to
