research description:

Several different scattering techniques (elastic and inelastic neutron scattering, x-ray diffraction, and low-energy electron diffraction) are being employed to study the physical properties of films as thin as a single molecular layer. Interest in these quasi two-dimensional (2D) films is based on the premise that phenomena such as crystal growth, structural phase transitions, and changes of state (e.g., melting) will be easier to understand in lower dimensional systems. In some cases, a theory may be easier to formulate conceptually in 2D as in elucidating steps in the melting process. In other cases, it may be easier to implement a model mathematically in 2D rather than 3D. Experimental investigation of these thin films requires some method of holding the sample. In our experiments, the molecules are physically adsorbed on a solid surface.
