By the theory of semiconductor physics, the band gap of most semiconductor materials will decrease with rising temperature.
Temperature changed in 250 K to 350 K process, the band gap materials of GaAs without AlN film decreased from 1.4246 eV to 1.3844 eV, decrease of 0.0402 eV, although this value was very small, then it was converted to a light wavelength, in fact the wavelength changed from 870.42 nm to 895.68 nm, wavelength was" redshift" of 25.2 nm, the average mobile speed was 2.52 nm / K.
