Using the above formula, we also obtain the temperature dependence formula. For this we
use Varshni's empirical expression.

Hence, substituting (7) into (6), we obtain the effect of the transverse quantizing magnetic
field on the temperature dependence of the band gap of a quantum well with a parabolic dispersion
