THz emission of narrow-gap HgCdTe films and HgTe/CdTe quantum well structures

Investigation into emission of THz radiation in narrow gap HgCdTe layers and QWs is presented. The results are compared with THz photoconductivity spectra and relaxation kinetics. A possibility of THz lasing in CdHgTe waveguide QW structures is discussed.
