    Led and Photodiode

    the conduction band of the n-type semiconducting material and holes are injected from high work function anode to the valence band ot the p-type semiconducting material. When the electron in the conduction band combines with the hole in the valence band, energy is released. In case of indirect band gap semicondutors, phonon will be released to conserve of both energy and momentum. But in case of direct band gap semiconductor, light will be emitted whose wavelength depends on the band gap of the semiconductor
