Question

Three semiconductors are arranged in the increasing order of their energy gap as follows: the correct arrangement is

• A. Tellurium, germanium, silicon
• B. Tellurium,silicon , germanium
• C. silicon, germanium, Tellurium
• D. silicon, Tellurium, germanium

Answer 1

The correct option is A Tellurium, germanium, silicon

The energy gap of Tellurium is $\text{0}\text{.368 eV}$ at normal temperature.

The energy gap of Germanium is $\text{0}\text{.67 eV}$ at normal temperature.

The energy gap of Silicon is $\text{1}\text{.1 eV}$ at normal temperature.

Hence, the correct order is Tellurium < Germanium < Silicon
