Functionalization of germanium nanowires

Research output: Chapter in Book/Report/Conference proceedingsChapterpeer-review

Abstract

Halogen-termination and organic functionalization of germanium (Ge) nanowires is described. X-ray photoelectron spectroscopy (XPS), X-ray photoemission electron spectroscopy (XPEEM), infrared spectroscopy (IR) and transmission electron spectroscopy (TEM) were used to characterize the modified nanowire surfaces. The stability of alkyl and alkanethiol monolayers formed on Cl, Br and I-terminated surfaces are compared. The direct covalent attachment of aryl ligands onto H-Ge nanowires can be achieved by the decomposition of arenediazonium salts in acetonitrile solutions. The influence of the ring substituent on the thickness and uniformity of the functionalization layer was investigated.
