TeO2 NANOWIRE FORMING METHOD CAPABLE OF CONTROLLING TEMPERATURES AND SPEEDS FOR GROWTH BY USING GOLD AS A CATALYST

摘要

PURPOSE: A TeO2 nanowire forming method is provided to control the diameter and speed of growth to gain regular TeO2 nanowire with a small diameter.;CONSTITUTION: A TeO2 nanowire forming method comprises the following steps. In a chamber(100) for growth, gold(Au) coated plate(110) and a tellurium(Te) source are arranged but they are not connected. The inside of the chamber is heated at a temperature over 330°C and below 400°C to grow TeO2 nanowire(150) on the plate. The distance from the plate to the tellurium is 1-10mm. The tellurium source is powder type and is prepared on a plate(120).;COPYRIGHT KIPO 2013
