Abstract:
1. A method for growth of an alloy for use in a nanostructure, the method comprising: providing a substrate comprising Si, on which is deposited at least one of (i) a thin film coating of Au and (ii) a spaced apart array of thin particles of at least one of Au, Ni, Ti, Cr, In, Sb, Ge and Te, having a thickness in a range of 0.5-100 nm, with a substrate temperature in a range of about 330° C.-550° C., where at least a portion of the thin film coating or thin particle array serves as a catalyst for growth of nanostructures on a selected surface of the substrate; providing at least first and second chemical sources, with the first source comprising Ge allowing at least a portion of the first source and at least a portion of the second source to become first and second vapors, respectively, and to combine to form a resulting vapor comprising Ge exposing the selected surface of the substrate to the vapor comprising Ge
