摘要：

Transition metal telluride CoTe nanostructures have been synthesized using a wet-chemical method. These nanostructures exhibit NiAs-type hexagonal crystal structure with a space group of P63/mmc. The magnetic measurements show spontaneous magnetization and hysteresis, and the coercivity increases with a decrease in temperature. The saturation magnetization was calculated to be around 0.2 mu(B)/Co atom. The magnetic transition temperature was found to be above room temperature similar to that of the bulk CoTe. The measured bandgap of the nanostructures is 2.15 eV and they exhibit p-type semiconducting behavior. (C) 2016 American Vacuum Society.
