High Purity Germanium Based Radiation Detectors with Segmented Amorphous Semiconductor Electrical Contacts: Fabrication Procedures [PDF]

arXiv, 2020
Radiation detectors constructed from large volume high purity Ge (HPGe) single crystals are widely used for gamma-ray spectroscopy. The detectors for this application can be simple in that they need only have two electrical contacts for voltage application and signal readout.
