Physical principles of the amplification of electromagnetic radiation due to negative electron masses in a semiconductor superlattice

In a superlattice placed in crossed static electric and magnetic fields, under certain conditions, the inversion of electron population can appear at which the average energy of electrons is above the middle of the mini-band and the effective mass of the electron is negative. This is the implementat...
