Abstract
A method of synthesizing silicon wires generally includes the steps of: providing a substrate; forming a copper catalyst particle layer on a top surface of the substrate; heating the reactive device at a temperature of above 450° C. in a flowing protective gas; and introducing a mixture of a protective gas and a silicon-based reactive gas at a temperature of above 450° C. at a pressure of below 700 Torr, thereby forming the silicon wires on the substrate.
Claims4
A synthesis method of silicon wires comprising:
- providing a substrate;
- forming a layer containing a cupric chloride or cupric sulfate on a top surface of the substrate, the layer containing the cupric chloride or cupric sulfate being in a form of one of a powder and a liquid solution;
- and
- heating the substrate with the layer containing the cupric chloride or cupric sulfate thereon in a flowing protective gas to decompose the cupric chloride or cupric sulfate to thereby form a copper catalyst particle layer on the substrate;
- and
- introducing a mixture of the protective gas and a silicon-containing reactive gas at a temperature of above about 450° C. and at a pressure of below about 700 Torr, thereby forming the silicon wires on the substrate.
