|Title:||Formation of covalent Si-N linkages on pyrrole functionalized Si(100)-(2×1)||Authors:||Qiao, M.H.
|Issue Date:||4-Aug-2000||Citation:||Qiao, M.H.,Cao, Y.,Deng, J.F.,Xu, G.Q. (2000-08-04). Formation of covalent Si-N linkages on pyrrole functionalized Si(100)-(2×1). Chemical Physics Letters 325 (5-6) : 508-512. ScholarBank@NUS Repository.||Abstract:||The covalent attachment of a pyrrolyl monolayer has been efficiently achieved by directly exposing pyrrole molecules to the clean Si(100)-(2×1) surface. The high-resolution electron energy loss spectroscopy (HREELS), and X-ray photoelectron spectroscopy (XPS) studies show that the robust pyrrolyl monolayer is directly bonded to the Si(100) surface via the Si-N linkage with the preservation of the pyrrolyl ring structure. The as-prepared pyrrole-modified silicon surfaces can serve as templates for further electrochemical polymerization of polypyrrole thin films onto silicon substrates, providing new opportunity for fabrication of new polypyrrole/silicon heterojunctions with improved performance.||Source Title:||Chemical Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/93843||ISSN:||00092614|
