Two-dimensional ordering in Langmuir monolayer and Langmuir-Blodgett films

Milan Sanyal (Saha Institute of Nuclear Physics - Kolkata, India)

Molecular materials and nanoparticles having hydrophilic and hyphobic parts easily form monolayer at liquid-vapor and liquid-liquid interfaces. One can deposit multilayered films with these monolayers by transferring these materials sequentially on a substrate. Fascinating ideas of two-dimensional physics can be studied using these monolayers and multilayers. We shall discuss our recent results of synchrotron x-ray and polarized neutron scattering studies to understand two-dimensional structural and magnetic ordering, respectively, in these systems.
