Which Estimates the Number of Electrons Per Cubic Centimeter Excited

Which estimates the number of electrons per cubic centimeter excited to the conduction band as a function of temperature and the band gap energy.

-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
