DNA-Mediated Electrochemistry [PDF]

, 2008
The base pair stack of DNA has been demonstrated as a medium for long-range charge transport chemistry both in solution and at DNA-modified surfaces. This chemistry is exquisitely sensitive to structural perturbations in the base pair stack as occur with

Controlling charge injection in organic field-effect transistors using self-assembled monolayers [PDF]

, 2006
We have studied charge injection across the metal/organic semiconductor interface in bottom-contact poly(3-hexylthiophene) (P3HT) field-effect transistors, with Au source and drain electrodes modified by self-assembled monolayers (SAMs) prior to active ...

The electrochemical stability of thiols on gold surfaces [PDF]

, 2019
In this paper we present a comparative analysis of the electrochemical stability of alkanethiols, aromatic and heterocyclic thiols on the Au(111) and Au(100) faces in relation to the theoretical energetic data. The peak potential and surface coverage are

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Non-Amontons behavior of friction in single contacts

, 2005
We report on the frictional properties of a single contact between a glassy polymer lens and a flat silica substrate covered either by a disordered or by a self-assembled alkylsilane monolayer.

From Monomers to Self-Assembled Monolayers: The Evolution of Molecular Mobility with Structural Confinements [PDF]

, 2014
The effect of structural constriction on molecular mobility is investigated by broadband dielectric spectroscopy (BDS) within three types of molecular arrangements: monomers, oligomers and self-assembled monolayers (SAMs).

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Wafer‐Scale, Highly Uniform Surface Functionalization from Vapor Phase and Applications to Organic Transistors

Advanced Materials Interfaces, 2023
The surface functionalization by self‐assembled monolayers (SAMs) favors well‐packed organic semiconductor growth and reduces interfacial traps, which assists in developing high‐performance organic thin‐film transistors (OTFTs).
