Synthesis and characterization of Cobalt Telluride Nanotubes

Cobalt telluride nanotubes have been synthesized by means of a wet chemical synthesis. High quality cobalt telluride nanotubes were prepared through a two step process. Initially, tellurium nanowires were synthesized at 160 $^{\circ}$C from TeO$_{3}$ and then cobalt precursor was injected into the solution containing tellurium nanowires at 180 $^{\circ}$C. Cobalt diffusion into tellurium nanowires were not complete if the temperature was maintained below 180 $^{\circ}$C. These CoTe nanotubes exhibit hexagonal crystal structure. They are ferromagnetic at 10 K.
