METHOD FOR MANUFACTURING ROOM TEMPERATURE NANOBELTS ZNS FERROMAGNETIC SEMICONDUCTOR

摘要

A method for manufacturing room temperature nano-belts ZnS ferromagnetic semiconductor is provided to realize spintronics by growing ZnS nano-belts doped with Mn and Fe on a substrate. A semiconductor manufacture apparatus is comprised of a reaction chamber(1), a quartz tube(3), and an alumina boat(7) for accommodating a mixed powder. A substrate(5) coated with Au colloid and a mixed powder made of ZnO, FeS, and MnCl2 are placed in an inner of the reactive chamber. The mixed powder is heated to be vaporized. Upon supplying Ar gas into the reactive chamber and moving the vaporized mixed powder, ZnS nano-belts doped with Mn and Fe is grown on the substrate.
