Question

Approximately how much thermal energy is available at room temperature (RT)?

Options

• \[0.026\ \mathrm{eV}\]

• \[0.7\ \mathrm{eV}\]

• \[5.4\ \mathrm{eV}\]

• \[1.1\ \mathrm{eV}\]

Answer 1

Thermal energy at room temperature is approximately \[0.026\ \mathrm{eV}\]. This is far too small to excite electrons across the very large energy gap of an insulator.
