Voltammetric Properties of the Reductive Desorption of Alkanethiol Self-Assembled Monolayers from a Metal Surface
TL;DR: In this article, a linear-scan voltammogram for the reductive desorption of alkanethiol self-assembled monolayers (SAMs) from a gold surface in an aqueous alkaline solution exhibits intriguing features: the narrow full width at half-maximum (fwhm) of the peak, e.g., 20 mV for dodecanethiol SAMs, the saturation of fwhm in the SAM composed of long-chain alkarnethiols, an asymmetric shape, the shift of peak potential with increasing the

TL;DR: Hopping and band mobilities of holes in organic semiconductors at room temperature were estimated from first principle calculations and it is found that van der Waals interactions play an important role in determining accurate relaxation times.
Journal ArticleDOI
Chain-length-dependent change in the structure of self-assembled monolayers of n-alkanethiols on Au(111) probed by broad-bandwidth sum frequency generation spectroscopy
TL;DR: The structure of the self-assembled monolayers (SAMs) of n-alkanethiols [CH3(CH2)nSH, n=3-11, 13-15, 17] on Au(111) has been studied using broad-bandwidth sum frequency generation spectroscopy.
Journal ArticleDOI
Surface structure of binary self-assembled monolayers formed by electrochemical selective replacement of adsorbed thiols
TL;DR: In this paper, a phase-separated binary self-assembled monolayers (SAMs) prepared by the electrochemical selective replacement of adsorbed thiols in phase separated binary SAMs has been studied by scanning tunneling microscopy (STM) and cyclic voltammetry.

TL;DR: In this article, the miscibility of a binary self-assembled monolayer (SAM) of 1-undecanethiol (UDT) and 11-mercaptoundecanoic acid (MUA) on Au(111) has been studied using voltammetry of the reductive desorption of thiol, X-ray photoelectron spectroscopy, and scanning tunneling microscopy (STM).
