Random Walk Simulation for the Growth of Monolayer in Dip Pen Nanolithography
Dip-pen nanolithography (DPN) has emerged as a general tool for fabricating nanopatterns on a range of substrates, including metallic, insulating and semiconducting substrates. In DPN, an atomic force microscope (AFM) tip functions as a source to continuously create nanodroplets of molecules that then spread to form a self-assembled monolayer (SAM) on a substrate. Molecular transport from the t...
متن کامل"Dip-Pen" nanolithography
A direct-write "dip-pen" nanolithography (DPN) has been developed to deliver collections of molecules in a positive printing mode. An atomic force microscope (AFM) tip is used to write alkanethiols with 30-nanometer linewidth resolution on a gold thin film in a manner analogous to that of a dip pen. Molecules are delivered from the AFM tip to a solid substrate of interest via capillary transpor...

In recent years, SPM-based lithography has attracted great attention because of its simplicity and precise control of the structure and location. Many SPM lithography techniques based on mechanical scratching,1 anodization of Si surfaces,2 electrochemical decomposition of self-assembled monolayers,3 electric field-induced chemical reactions,4 electrochemical reactions in solution using electroc...
متن کاملA diffusive ink transport model for lipid dip-pen nanolithography.
Despite diverse applications, phospholipid membrane stacks generated by dip-pen nanolithography (DPN) still lack a thorough and systematic characterization that elucidates the whole ink transport process from writing to surface spreading, with the aim of better controlling the resulting feature size and resolution. We report a quantitative analysis and modeling of the dependence of lipid DPN fe...
متن کاملCapillary bridge rupture in dip-pen nanolithography.
Here, we explore fluid transfer from a nanoscale tip to a surface and elucidate the role of fluid flows in dip-pen nanolithography (DPN) of liquid inks. We find that while fluid transfer in this context is affected by dwell time and tip retraction speed from the substrate, their specific roles are dictated by the contact angle of the ink on the surface. This is shown by two observations: (1) th...
