The indium phosphide nano wire of the indium phosphide nano wire and its production

摘要

PROBLEM TO BE SOLVED: To provide indium phosphide nanowires each covered with a chemically inert carbon film, which are useful as a material for a high-speed electronic device or an optical device, and a method for producing the same.;SOLUTION: Indium phosphide nanowires are synthesized by heating a mixture 4 of an indium phosphide powder and an indium powder at 950-1,050°C for 0.5-0.8 h in an inert gas stream. Thereafter, each indium phosphide nanowire is covered with the carbon film by depositing the carbon film on the surface of each indium phosphide nanowire by subsequently heating the indium phosphide nanowires at 950-1,050°C for 10-30 min while making an inert gas and methane gas flow. The carbon film can prevent the deterioration of the properties of the indium phosphide nanowires by preventing the oxidation of them since it is chemically stable.;COPYRIGHT: (C)2006,JPO&NCIPI
