Abstract

Germanium, have been synthesized using chemical vapor deposition with Au nanoparticles (with size ranging from 5 nm to 30 nm) as nucleating centers (catalysts) and Germanium powders as a source for the nanowires growth. Au nanoparticles were synthesized on Si (100) by using simple and cost effective sol-gel process from HAuCl4 as a precursor. The monodisperse, molecular-scale, single-crystal Ge nanowires with diameters as small as 15 nm have been grown in a controllable manner. X-ray diffraction and high resolution scanning electron microscopy and X-ray photoelectron spectroscopy have been employed to characterize for their structural, morphological, and compositional properties. These nanowires are opening up unique opportunities for fundamental physics and high-performance devices also the nanowires could be used to create electronic devices for small, ultra fast computers and memories.
