Abstract
On the basis of the Hall effect measurements, the dependencies of the Hall EMF on the induction of an external magnetic field for the electron irradiated n-Ge single crystals, coated with a layer of the epoxy-dianon resin (without fillers and with fillers of the powders of iron and aluminum) have been obtained. These single crystals were irradiated by the electrons with an energy of 10 MeV and the flow of Ω=5·1015 el./cm2. From the analysis of these dependencies it follows that they are linear for germanium single crystals, coated with a layer of epoxy resin without filler and with the filler of aluminum powder in the whole range of investigated magnetic fields. For germanium samples, coated with a layer of epoxy resin with filler of an iron powder, there is a slight deviation from the linearity of such dependencies for the magnetic fields up to 0,3 T, which is explained by the additional magnetization of iron powder. It was established that the presence of a protective epoxy resin layer significantly reduces the sensitivity of germanium single crystals to the influence of an external magnetic field. The presence of residual magnetization for irradiated n-Ge single crystals, coated with an epoxy resin with the filler of iron powder can be used for developing an energy storage systems based on such single crystals.
