Step 1
We know that 1 eV = 1.6 x 10^-19 J. So, the energy E of the band gap is: E = 1.42 eV * 1.6 x 10^-19 J/eV = 2.27 x 10^-19 J Show more…

The band gap in gallium arsenide is $140 \mathrm{kJ} / \mathrm{mol}$. What is the maximum wavelength of light needed to excite an electron to move from the valence band to the conduction band?
A photon of monochromatic light of wavelength 500 nm is absorbed on GaAs and excites an electron from the valence band to the conduction band. Assuming that, the electron and the hole masses are equal, calculate the kinetic energy of the electron and the hole. The band-gap of GaAs is 1.43 eV at room temperature.
