The capture of free holes and electrons in germanium (Ge) doped by gallium (Ga) or antimony (Sb) has been studied by a time-resolved pump-probe experiment with the free-electron laser FELBE at the Helmholtz-Zentrum Dresden-Rossendorf. For Ga acceptors the relaxation times decrease with increasing pump power from approximately 3 ns to 1 ns (2 ns and 1 ns for Sb donors, respectively). The results support the development of fast photoconductive detectors in the terahertz frequency range.I.

The status of various photovoltaic, photoconductive, BIB/IBC, superlattice, TES and KID technologies to produce arrays sensitive from 15 to [Formula: see text]m (Mid-infrared) will be reviewed to assess where reasonable investments should be made for SOFIA and other sub-orbital observatory instruments. These include HgCdTe, Si:As IBC, Si:Sb BIB, Ge:Ga, type 2 superlattice arrays of both III–V and II–VI materials and both TES and KID arrays. KID technologies for this wavelength region show promise, although to date there are no published experimental data on KID arrays for the mid-infrared.
