A hot electron theory is applied to Landau levels of MUS inversion layers asthe first example of the theory for extremely quantized systems. The energy gainfrom drain fields and the energy loss to phonons are formulated in the self-consistent Born approximation. A difference between the electron temperatureand the lattice temperature in Landau levels is calculated by balancing these twoenergy terms. A larger temperature difference is expected for a larger Landauindex and is almost independent of the position where the Fermi level lies. Thetypical temperature rises are 1.4 K for A'=0, 3.0 K for V= 1, 4.1 K for N=2 and5.0 K for 7V=3, when the applied electric field is 20 V/cm, the applied magneticfield is 140 k0e and the lattice temperature is 1.4 K. The observed temperaturerises are little lower than the theoretical results.
