고리형 지방족 싸이올 단분자막의 구조에 대한 작용기 효과 = Effect of functional group on the structure of alicyclic thiol self-assembled monolayers on Au(111)

다국어 초록 (Multilingual Abstract)

Surface structures, adsorption conditions, and electrochemical behaviors of self-assembled monolayers (SAMs) formed by the adsorption of cyclohexanethiol (CHT), 4-hydroxylcyclohexanethiol (HCHT), 4-methylcyclo-hexanethiol (MCHT), adamantanethiol (AMT), and cyclohexyldiselenide (DCDSe), on Au(111) were characterized by means of scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), thermal desorption spectroscopy (TDS), contact angle (CA), and cyclic voltammetry (CV) measuraments.
