Abstract

Single-crystalline nanostructured Zn_1-xMn_xS, a diluted magnetic semiconductor, was achieved via a simple vapour phase deposition on silicon substrates. Morphology, structure, and composition of the nanostructured Zn_1-xMn_xS were studied by using x-ray diffraction, transmission electron microscopy, and energy-dispersive spectroscopy. The nanostructured Zn_1-xMn_xS is composed of nanowires and nanobelts, which are quite flexible and free of defects. Both of them have smooth and straight surfaces with lengths over 10 μm. They possess cubic structure with a principal axis along their axes. The nanostructured Zn_1-xMn_xS exhibits paramagnetic behaviour. Photoluminescence study shows a blue band and a yellow band, which are due to the surface states and the transitions of Mn²⁺ (⁴T ₁(G)-⁶A₁(S)), respectively. The growth of the nanostructured Zn_1-xMn_xS could be explained by a self-catalyst growth mechanism.
