CUET Preparation Today
The electrical conductivity of a semiconductor increases when electromagnetic radiation of wavelength shorter than 2480 nm is incident on it. The band gap (in eV) for the semiconductor is |
0.9 0.7 0.5 1.1 |
0.5 |
Band gap, $E_g=\frac{hc}{λ}=\frac{(6.6×10^{-34})(3×10^8)}{2480×10^{-9}×1.6×10^{-19}}eV=0.49eV$ |
