Classify solids into conductors, semiconductors and insulators by drawing energy diagram.

Classify the following into conductors, insulators, and semiconductors. Ga, As, Ni, Calcite, Graphite

What is energy gap in band theory? Compare its size in Conductors, semi Conductors and insulators?

The variation of resistivity (e) with temperature (T) of a conductor, semiconductor and super conductor are given in the figure. . Identify them from the graph.

We are familiar with the semiconductors Silicon and Germanium.With a necessary schematic diagram, briefly explain the characteristics of an intrinsic semicon ductor.

In terms of band theory differentiate Conductors, insulators & semi conductors
