Stimulated emission of plasmon-LO mode in narrow gap HgTe/CdHgTe quantum wells
2021
The possibility of amplification of the coupled plasmon – optical phonon (LO) mode in an HgTe quantum wells (QWs) is theoretically considered. In a 6 nm wide QW with CdTe barriers and in a 5 nm wide QW with Cd0.7Hg0.3Te barriers grown on the (013) plane, stimulated emission of the plasmon – LO mode is possible in the frequency range corresponding to the Reststrahlen band of GaAs.
