Temperature-dependent increase of the terahertz (THz) electric field emitted from the surfaces of optically pumped narrow-gap semiconductors InAs, InSb, and Cd x Hg 1Àx Te is presented. In the case of Cd 0.2 Hg 0.8 Te increase up to 15-17 times has been observed, when cooling the sample from the roo
