spie.orgavailable for germanium at an earlier date, the first high-performance extrin-sic detectors were based on Ge:Hg with activation energy for the Hg acceptor of 0.089 eV. Extrinsic photoconductive response from copper, zinc, and gold impurity levels in germanium gave rise to devices using the 8- to 14-mm long

Chapter 8 Hyper-Pure Germanium Detector
www.science.mcmaster.caIn both Si and Ge, the material with highest available purity tends to be p-type, which requires addition of donor atoms for compensation. The alkali metals like Li, Na tend to form interstitial donors in Si and Ge. When one of these donor materials (practically Li) is introduced into Si or Ge, the donor atoms are easily ionized

FTIR Spectroscopy: Attenuated Total Reflectance (ATR)
www.perkinelmer.com(ZnSe) and Germanium are by far the most common used for HATR sampling. Zinc Selenide is a rela-tively low cost ATR crystal material and is ideal for analyzing liquids and non-abrasive pastes and gels but it is not particularly robust with a working pH range of 5-9. ZnSe scratches quite easily and so care must be taken when cleaning the crystal ...
