Effect of growth parameters on surface morphology of sputtered zinc antimonides thin films

The growth and characterization of nanostructured zinc antimonides (Zn4Sb3) thin films are reported in this work. The nanostructured Zn4Sb3 thin films were prepared by RF magnetron sputtering using a single sputtering target made from a stoichiometric Zn4Sb3. The range of growth parameters were dete...

The nanostructured Zn4Sb3 thin films were prepared by RF magnetron sputtering using a single sputtering target made from a stoichiometric Zn4Sb3.
