Inversion of hot carriers in Landau levels
Kozlov V. A., Mazov L. S., Nefedov I. M., Zabolotskikh M. R.
A method is proposed for creating an inverted population of hot carriers in Landau levels of the light subband in crossed Ε and В fields. Impurity scattering in this case facilitates inversion and for it "ultrapure" semiconductors are not required.
