Scanning probe lithography of self-assembled monolayers
Systematic studies on scanning probe lithography (SPL) methodologies have been performed using self-assembled monolayers (SAMs) on Au as examples. The key to achieving high spatial precision is to keep the tip-surface interactions strong and local. Approaches include three atomic force microscopy (AFM) based methods, nanoshaving, nanografting, and nanopen reader and writer (NPRW), which rely on...
متن کاملCatalytic probe lithography: catalyst-functionalized scanning probes as nanopens for nanofabrication on self-assembled monolayers.
This article describes the use of scanning catalytic probe lithography for nanofabrication of patterns on self-assembled monolayers (SAMs) of reactive adsorbates. Catalytic writing was carried out by scanning over bis(omega-tert-butyldimethyl-siloxyundecyl)disulfide SAMs using 2-mercapto-5-benzimidazole sulfonic acid-functionalized gold-coated AFM tips. The acidic tips induced local hydrolysis ...
متن کاملElectronic transport in self-assembled alkanethiol monolayers
Electron tunneling through self-assembled monolayers of alkanethiols is investigated. Temperature-dependent current– voltage measurements are performed to distinguish between di erent conduction mechanisms. Temperature-independent electron transport is observed, proving direct tunneling as the dominant conduction mechanism of alkanethiols. An exponential dependence of tunneling current on molec...
متن کاملSelf-Assembled Monolayers of Azobenzene-Incorporated Alkanethiol on Silver
In the past decade, self-assembled monolayers (SAMs) have received a great deal of attention for their fundamental importance in understanding interfacial properties as well as for their potential applications in molecular technologies. SAMs have been used in the design of various interfaces for chemical sensors, nonlinear optical materials, optical switches, and high density memory devices. Th...
متن کاملSurface stress, kinetics, and structure of alkanethiol self-assembled monolayers.
The surface stress induced during the formation of alkanethiol self-assembled monolayers (SAMs) on gold from the vapor phase was measured using a micromechanical cantilever-based chemical sensor. Simultaneous in situ thickness measurements were carried out using ellipsometry. Ex situ scanning tunneling microscopy was performed in air to ascertain the final monolayer structure. The evolution of ...
