摘要: Molecular dynamics (MD) calculations are used to study the contact behavior of self-assembled monolayer (SAM) deposited on gold substrate in dip-pen nanolithography (DPN). The interaction SAM atoms was described by a general universal force field, tight-binding, second-moment approximation for Au substrate, and Lennard-Jones potential function employed describe between atoms. MD model consists planar with n-hexadecanethiol chemisorbed substrate. When clusters brought closer surface, normal is induced. increases as size increases. In addition, effect temperature angle alkanethiol DPN evaluated. Results show that angles decreased increased, smaller cluster size, angle.
