The electrical conductivity of a semiconductor of a semiconductor increases when electromagnetic radiation of wavelength shorter than 2480 nm, is incident on it. The band gap in (eV) for the semi conductor is …… |
|
Answer» 0.5 EV BAND gap energy `E_(g)=h_(f)` `=(hc)/(lambda)` `=(hc)/(lambda e)"" `(In eV) `=(6.63xx10^(-34)xx3xx10^(8))/(2480xx10^(-9)xx1.6xx10^(-19))` `=0.0050126xx10^(2)` `~~0.5eV` |
