WitrynaImpurities in the crystals trap electrons and holes, ruining the performance of the detectors. Consequently, germanium crystals were doped with lithium ions (Ge (Li)) to … Witryna14 sty 2016 · The impurity band has a shallower energy level and thus can extend FIR wavelength coverage up to \sim 200 \upmu m. However, the impurity band also produces large leakage current. In order to block the current, the blocking layer is inserted between the heavily doped Ge:Ga layer and an electrode.

In these papers the results of 5 different authors are shown. In regard to Ge, at low temperatures (4.2K), the energy-gap vs. impurity concentration dependence is shown in [3].
