Options

A. `E_(g)` (diamond) `gtE_(g)` (silicon)`gtE_(g)` (germanium)
B. `E_(g)` (daimond) `ltE_(g)` (silicon) `ltE_(g)` (germanium)
C. `E_(g)` (diamond) `=E_(g)` (silicon) `=E_(g)` (germanium)
D. `E_(g)` (diamond `gtE_(g)` (germanium) `gtE_(g)` (silicon).

Answer

a

Explanation

Semiconductors are solids where there is only a small difference in energy, called a band gap' between the filled valence band of electrons and a conduction band.
