Energy gap, Eg=(h c/λ )=(11250/0 . 75)=15000 mathringA

Q. The forbidden energy gap in $G e$ is $0.75 e V$ , given $h c = 11250 e V \overset{˚}{A}$ The maximum wavelength of radiation that will generate electron hole pair is

$1500 \overset{˚}{A}$

$15000 \overset{˚}{A}$

$150.52 \overset{˚}{A}$

$150 \overset{˚}{A}$

Energy gap, $E_{g} = \frac{h c}{λ} = \frac{11250}{0.75} = 15000 \overset{˚}{A}$
