Popis: |
An intense terahertz emission of stimulated character from boron-δ-doped Si/Si1−xGex/Si quantum well structures has been observed. The stimulated emission arises under strong electric fields (300– 1500 V / cm ) applied parallel to interfaces. The mechanism of population inversion is based on the formation of resonant acceptor states in strained SiGe layer. |
