چکیده
|
Tellurium nanostructures have been prepared by physical vapor deposition method in a tube furnace. the experiments were carried out under argon gas flow at a pressure of 1 mbar. tellurium powder was evaporated by heating at 350°c and 430°c and was condensed on substrates at 110–250°c, in the downstream of argon gas flow. the products were characterized by field emission scanning electron microscopy (fesem) and x-ray diffraction (xrd). fesem revealed that most of the products have one dimensional structure. x-ray diffraction (xrd) patterns show that the products are crystalline with hexagonal structures
