Consider an intrinsic semiconductor with an electronic density of states function N(E) , as shown in Fig. Estimate the density of conduction band electrons at room temperature.
1
\( n \approx 4.68 \times 10^9 \, \text{cm}^{-3} \)
2
\( n \approx 4.68 \times 10^5 \, \text{cm}^{-3} \)
3
\( n \approx 4.68 \times 10^6 \, \text{cm}^{-3} \)
4
\( n \approx 4.68 \times 10^7 \, \text{cm}^{-3} \)
