Q175 / 180 · KCET 2017 · Physics

The energy gap in case of which of the following is less than \( 3 \mathrm{eV} ? \)

A
Copper
B
Iron
C
Alumunium
Correct answer
D
Germanium

Solution

The energy gap of Germanium is \( 0.7 \mathrm{eV} \), that is, \( < 3 \mathrm{eV} \)

Hence, the correct answer is option: 'D'.
