Block Copolymer Self-assembly on Ethylene Glycol (EG) Self-assembled Monolayer (SAM) for Nanofabrication

MRS Proceedings, 2012
ABSTRACTNanostructure templates fabrication from P(S-b-MMA) thin films requires precise control of interfacial energies to achieve perpendicular orientation of microdomains to the substrate surface and can be obtained by modifying the oxide layer on silicon with a covalently anchored hydroxyl-terminated random copolymer P(S-r-MMA) termed a “neutral ...

Properties of self‐assembled monolayers (SAMs) from thiol‐functionalized oligothiophenes

Advanced Materials, 1997
The introduction of electroactivity into a self‐assembled monolayer (SAM) has been attempted as a step towards a tunable interface between metals and conjugated conducting polymers. The synthesis of terthiophenes bearing an alkylthiol function at their terminal position and their chemisorption onto platinum single crystals are described. The properties

Self‐assembled monolayers (SAMs) of porphyrin deposited inside photonic crystal fibre (PCF)

physica status solidi (a), 2011
AbstractWe report on the surface modification of the channels of hollow‐core photonic bandgap fibres after deposition of free‐base porphyrins by self‐assembling monolayer (SAM) technique. Emission spectra studies of the modified fibres showed features typical for free‐base porphyrins deposited on glass plates.

Enhanced Stability of Thiolate Self-Assembled Monolayers (SAMs) on Nanostructured Gold Substrates

Langmuir, 2009
Degradation of thiolate self-assembled monolayers (SAMs) in ambient conditions and liquid environments seriously limits the fabrication of thiol-based devices. Here, we demonstrate that nanostructured gold exhibits higher resistance to SAM degradation and increased electrochemical stability against thiolate desorption in relation to polycrystalline ...

A Suspended Au Nanowire Bridge with Functionalized Self-Assembled Monolayers (SAMs)

2006 Sixth IEEE Conference on Nanotechnology, 2006
In this paper, a very simple top-down nanofabrication method, which is compatible with standard silicon (Si) fabrication processes, is proposed to fabricate a new suspended gold (Au) nanowire bridge. The electrical characteristics of the nanowire bridges with different design parameters are measured.

High sensitivity IR spectroscopic methods of self-assembling monolayers (SAM) measurements

Applied Surface Science, 2007
New systems of coupling the FTIR spectrum signal amplification, mainly for self-assembling monolayers (SAMs) investigation, were developed. These systems based on hollow waveguide (HW) or half cylinder mirror, which have negligible attenuation in the mid infrared; enable to obtain high signal sensitivity of the samples absorption due to the very high ...

Chapter 6 Micro/Nanolithography Using Self-Assembled Monolayers (SAMs)

2007
Publisher Summary This chapter focuses on the definition, preparation methods, usefulness, and various applications of self-assembled monolayer (SAM). Self-assembled monolayer is a single layer of organic molecules formed on a substrate in a liquid or gas phase. When a suitable combination of a substrate material and organic molecules is selected and

Self‐Assembled Monolayers (SAMs) and Synthesis of Planar Micro‐ and Nanostructures

Journal of Macromolecular Science, Part C: Polymer Reviews, 2004
Abstract A polymer is a macromolcule made up of multiple equivalents of one or more monomers linked together by covalent bonds. Self‐assembled monolayers (SAMs) are highly ordered molecular assemblies formed by chemisorption of functionalized molecules on the surface. Various system of SAMs are reviewed in this article.

Nanoscale Patterning Using Femtosecond Laser and Self-assembled Monolayers (SAMs)

Transactions of the Korean Society of Mechanical Engineers A, 2004
Standard positive photoresist techniques were adapted to generate nano-scale patterns of gold substrate using self-assembled monolayers (SAMs) and femtosecond laser. SAMs formed by the adsorption of alkanethiols onto gold substrate are employed as very thin photoresists, Alkanethiolates formed by the adsorption of alkanethiols are oxidized on exposure ...
