High purity Ge (HPGe) is the key material for gamma ray detector production. Its high purity level (< 2x10^(-4) ppb of doping impurity) has to be preserved in the bulk during the processes needed to form the detector junctions. With the goal of improving the device performance and expanding the application fields, in this paper many alternative doping processes are evaluated, in order to verify their effect on the purity of the material. In more detail, we investigated the electrical activation…
