WebThe FWHM for germanium detectors is a function of energy. For a 1.3 MeV photon, the FWHM is 2.1 keV, which is very low. On the other hand, germanium has a small band gap energy (E gap = 0.67 eV), which requires operating the detector at cryogenic temperatures. At room temperatures, the noise caused by thermal excitation is very high.
