Formation of Tellurium Nanotubes Through Concentration Depletion at the Surfaces of Seeds

Tellurium nanotubes with well-controlled structures (see Figure) are obtained via concentration depletion at the surfaces of seeds. The lengths of these inorganic nanotubes can be varied by adjusting the growth time (see cover), and the outer diameters of the tubes can be controlled by changing the initial concentration of the precursor acid.
