Highly ordered assembly of single-domain dichloropentacene over large areas on vicinal gold surfaces.

چکیده
Defining pathways to assemble long-range-ordered 2D nanostructures of specifically designed organic molecules is required in order to optimize the performance of organic thin-film electronic devices. We report on the rapid fabrication of a nearly perfect self-assembled monolayer (SAM) composed of a single-domain 6,13-dichloropentacene (DCP) brick-wall pattern on Au(788). Scanning tunneling microscopy (STM) results show the well-ordered DCP SAM extends over hundreds of nanometers. Combining STM results with insights from density functional theory, we propose that a combination of unique intermolecular and molecule-step interactions drives the DCP SAM formation.

Controlled surface functionalization via self-selective metal adsorption and pattern transformation on the vicinal Si(111) surface
We demonstrate a self-selective metal adsorption and pattern transformation process on vicinal Si 111 surfaces. When Au atoms are deposited onto the self-organized periodic Si 111 surface patterns, the Au atoms self-select to adsorb predominantly onto one of the two distinct domains, the Si 111 terrace or the stepbunched facet at different Au coverage. This leads to a systematic transformation ...
متن کاملFabrication of Highly Ordered Gold Nanorods Film Using Alumina Nanopores
A simple method for fabrication of highly ordered gold nanorod film is introduced in this article. The procedure is based on thermal evaporation of gold into a porous anodic alumina film (PAA). The PPA film was fabricated by combining the hard and mild anodization. This combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with c...
متن کاملLarge ordered arrays of single photon sources based on II-VI semiconductor colloidal quantum dot.
In this paper, we developed a novel and efficient method of deterministically organizing colloidal particles on structured surfaces over macroscopic areas. Our approach utilizes integrated solution-based processes of dielectric encapsulation and electrostatic-force-mediated self-assembly, which allow precisely controlled placement of sub-10nm sized particles at single particle resolution. As a ...
متن کاملShape-dependent ordering of gold nanocrystals into large-scale superlattices
Self-assembly of individual building blocks into highly ordered structures, analogous to spontaneous growth of crystals from atoms, is a promising approach to realize the collective properties of nanocrystals. Yet the ability to reliably produce macroscopic assemblies is unavailable and key factors determining assembly quality/yield are not understood. Here we report the formation of highly ord...
متن کاملFabrication of Highly Ordered Polymeric Nanodot and Nanowire Arrays Templated by Supramolecular Assembly Block Copolymer Nanoporous Thin Films
Realizing the vast technological potential of patternable block copolymers requires both the precise controlling of the orientation and long-range ordering, which is still a challenging topic so far. Recently, we have demonstrated that ordered nanoporous thin film can be fabricated from a simple supramolecular assembly approach. Here we will extend this approach and provide a general route to f...
