(a)
Interpretation:
Germanium doped with arsenic should be classified as p or n -type semiconductor.
Concept introduction:
According to band theory, solids are classified as conductors, semiconductors, and insulators.
As per band theory, bands are a continuum of energy levels. The bands are of two types: valence band and conduction band.
The band that holds valence electrons is valence band and band that is slightly higher in energy than valence band is conduction band. On the basis of band theory, partly filled band shows conduction and are called conductors, and fully filled band doesn’t show conduction and are insulators.
(b)
Interpretation:
Germanium doped with boron should be classified as p or n -type semiconductor.
Concept introduction:
According to band theory, solids are classified as conductors, semiconductors, and insulators.

- 8.96 A business manager wants to provide a wider range of p- and n-type semiconductors as a strategy to enhance sales. You are the lead materials engineer assigned to communicate with this manager. How would you explain why there are more ways to build a p-type semiconductor from silicon than there are ways to build an n-type semiconductor from silicon?arrow_forward(a) Why electrical conductivity of the semiconductor increases with increase in temperature? Illustrate and explain the above effect with hypothetical band energy diagrams, showing one at 25 °C and another at 50 °C?
