Calculate the temperature at which the number of electrons in the conduction band of a semiconductor is four times the number at room temperature. Take the band gap energy to be
Let's solve this step by step manually. We are asked to find the temperature $T$ at which the number of electrons in the conduction band $n$ is 4 times the number at room temperature ($T_0 = 300\ \text{K}$), given: * Band gap $E_g = 1.2\ \text{eV}$ * $E_C - E_F = _______ _______ ___ ________ ______.
