Deposition of Extended Ordered Ultrathin Films of Au₃₈ (SC₂ H₄ Ph)₂₄ Nanocluster using Langmuir-Blodgett Technique

Langmuir-Blodgett technique is utilized to deposit ultrathin films of Au₃₈ (SC₂ H₄ Ph)₂₄ nanocluster onto solid surfaces such as mica and silicon. The morphologies of the films transferred at various surface pressures within the mono/bi/trilayer regime are studied by atomic force microscopy (AFM). The time spent on the water surface before the deposition has a decisive effect on the final ordering of nanoclusters within the network and is studied by fast AFM, X-ray reflectivity, and grazing-incidence wide-angle X-ray scattering.
