Abstract

We report the effects of a neutron-capture reaction of isotope B 10 on the structure and electrical transport of B 10 -enriched single-crystalline boron nanobelts. Partial amorphization, particularly at the surface of the nanobelt, was observed after thermal neutron irradiation with a dose of 2× 10 19 cm-2. Carrier doping into the nanobelts by neutron transmutation is expected after postannealing. The change in conductance is discussed based on the distribution of localized states in the band gap of α -tetragonal boron.
