Graphene and prospects of radiation-hard hall sensors

The paper presents the results of studies of monoatomic layers of graphene obtained using the CVD method on a copper foil, followed by transfer to a sapphire substrate. The basic electrophysical parameters of graphene samples were measured. Their irradiation with neutrons in the nuclear research IBR-2 reactor was carried out up to the fluences of 4.5·10
¹⁹
n·m
⁻²
. A comparison of the Raman spectra before and after irradiation showed the stability of the structure of irradiated graphene.
