Multiple Choice

Exhibit 22-2
The following question(s) pertain to the following equation which estimates the number of electrons per cubic centimeter excited to the conduction band as a function of temperature and the band gap energy. $\mathrm{n}_{\mathrm{e}}=\left(4.8 \times 10^{15} \mathrm{~cm}^{-3} \mathrm{~K}^{-3 / 2}\right) \mathrm{T}^{3 / 2} \mathrm{e}^{-\mathrm{E}_{\mathrm{e}} /(2 \mathrm{RT}) }$
Refer to Exhibit 22-2. Based solely on the equation above, which set of conditions will result in the most electrons being excited to the conduction band.

• A) Low temperature, low band gap energy
• B) Low temperature, high band gap energy
• C) High temperature, low band gap energy
• D) High temperature, high band gap energy
