Abstract
THz emission of stimulated character was observed in Si/SiGe/Si quantum well (QW) structures doped with boron. The resonance cavity formed by extremely parallel-structure planes due to total internal reflection, is necessary for the emission. The mechanism for the possible population inversion of strain-split acceptor levels is proposed.
