Dependences of electron concentration, specific conductivity, and the Hall emf on the induction of an external magnetic field were obtained from Hall measurements of n-Si single crystals irradiated by electrons of 12 MeV energy and a flow of Ω = 1 × 1017 electron/cm2, coated with a layer of ED-20 epoxy resin. The composite layer was without fillers and with iron and aluminum powders as fillers. The presence of such a coating layer increases the radiation resistance of n-Si single crystals. Silicon single crystals coated with epoxy composite with an iron powder filler had the highest radiation resistance. The obtained dependences of the Hall emf on the induction of a magnetic field for the investigated n-Si samples are linear at magnetic fields above 0.3 T. At magnetic fields below 0.3 T, only the silicon single crystals coated with epoxy with an iron powder filler exhibited a slight deviation from linearity. This is due to additional magnetization of iron powder whose magnetic field affects the Hall emf. The obtained results can be used in designing radiation-resistant magnetically sensitive elements for Hall sensors. [ABSTRACT FROM AUTHOR] |
