Deposition of Extended Ordered Ultrathin Films of Au 38 (SC 2 H 4 Ph) 24 Nanocluster using Langmuir–Blodgett Technique

International audience; Langmuir–Blodgett technique is utilized to deposit ultrathin films of Au$_{38}$(SC$_2$H$_4$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.
