Molecular Dynamics of Self-Assembled Monolayer Formation in Soft Nanolithgoraphy
Molecular dynamics simulation is performed to study the growth mechanism of self-assembled monolayer in the AFM tip-assisted soft nanolithography such as in dip-pen nanolithography. We investigate how the droplet created around the tip spreads out to become a monolayer on the substrate. The previous diffusion model assumes that molecules diffuse on top of molecules already adsorbed on the subst...
متن کاملOptical absorption signature of a self-assembled dye monolayer on graphene
A well-organized monolayer of alkylated perylene-3,4,9,10-tetracarboxylic-3,4,9,10-diimide (PTCDI) has been formed onto CVD graphene transferred on a transparent substrate. Its structure has been probed by scanning tunnelling microscopy and its optical properties by polarized transmission spectroscopy at varying incidence. The results show that the transition dipoles of adsorbed PTCDI are all o...
متن کاملMolecular dynamics simulation study on a monolayer of half [2]rotaxane self-assembled on Au(111).
The self-assembled monolayer (SAM) structure of the tetrathiafulvalene-side half of the Stoddart-Heath type [2]rotaxane on Au(111) surface was investigated using molecular dynamics (MD) simulations. We find that the orientation of the cyclobis(paraquat-p-phenylene) (CBPQT) ring depends dramatically on the coverage, changing in order to obtain highly packed SAMs. The ring lies with its large hol...
متن کاملSelf-assembled Monolayer Films: Microcontact Printing
, Microcontact printing (PCP), one of the non-photolithographic techniques that make up "soft lithography" (Xia and Whitesides 1998), uses an elastomeric stamp to generate two-dimensional patterns by print* ing the molecules of an "ink" onto the surface of a solid substrate. In its most common configuration, the stamp is fabricated from an elastomeric polymer, poly(dimethylsiloxane) (PDMS), the...
متن کاملMultidentate adsorbates for self-assembled monolayer films.
The spontaneous adsorption of organic molecules on a variety of planar and nonplanar substrates, that is, self assembly, can generate films just one molecule thick. These nanoscale, self-assembled monolayer (SAM) films have been extensively used to engineer surfaces with well-defined properties. Their utility has been demonstrated in a wide range of applications, including wetting, adhesion, lu...
