Effect of Neutron Exposure on Transport of Charge Carriers in Poly-Crystalline Cu Nanowires
In the present work, the effect of neutron exposure on the electrical conductivity of 100 nm Cu nanowires (prepared by technique of electrodeposition using track-etched membranes) has been observed. In the different cases of neutron exposure to nanowires, the electrical conductivity initially remains less then pristine case, but exceeds when current through nanowire approaches 1 A. Though the electrical conductivity is found to increase in a linear manner with increase in applied potential difference, but the rate of increase is different for different exposure to neutrons. Neutrons induced modifications in the properties of a grain may be significant for parabolic nature of I–V characteristics (IVC), which follow a linear pattern (Ohm's law) before their exposure to neutrons. Transport of charge carriers through nanowires is the result of two competitive processes- specular and diffusive scattering of charge carriers (electrons) from grain boundaries, which is a region of high resistance than intra-grain regions. The flow of charge carriers in nanowires has been discussed in light of Mayadas and Shatzkes (MS) model with a slight modification for neutron exposed poly-crystalline Cu nanowires.
