Theoretical calculation of Radiation Induced Conductivity in nanomaterials

Radiation Induced Conductivity (RIC) is the increase in the conductivity of a material due to incident high energy ionizing radiations. The energy of such radiations excites the valence electrons into higher energy levels in the conduction band. Standard theories of RIC predict that the change in the conductivity of a material under radiation is proportional to radiation dose rate. Here, we show that for nanomaterials, the proportionality parameters in RIC depend on the size of irradiated nanomaterials.
