Dynamics Simulation of Langmuir-Blodgett Films

Abstract

Langmuir-Blodgett film monolayers are formed when amphiphilic molecules in solution are deposited on water surface followed by compression. During the compression, the randomly oriented molecules reorient themselves with the hydrophilic head groups on the water surface and the hydrophobic tail standing away from the water surface. The organic ultra-thin films with highly ordered layer structure, have shown a wide range of potential applications in biochemistry, microelectronics, integrated optics, microlithography, and many other fields. It is very important to get a better understanding of the relationship between the properties of the films and the micro-structure, for example, the molecular conformation, packing, orientation and motion in the films. For this purpose, within the past few years, different computer simulation methods were applied on LB film monolayers, including Monte Carlo methods and molecular dynamics simulations. (JS)
