نویسندگان
چکیده
Langmuir–Blodgett technique is utilized to deposit ultrathin films of Au38(SC2H4Ph)24 nanocluster onto solid surfaces such as mica and silicon. The morphologies the transferred at various surface pressures within mono/bi/trilayer regime are studied by atomic force microscopy (AFM). time spent on water before deposition has a decisive effect final ordering nanoclusters network fast AFM, X-ray reflectivity, grazing-incidence wide-angle scattering.

Switching adsorption and growth behavior of ultrathin [C2C1Im][OTf] films on Au(111) by Pd deposition.
Combining in vacuo deposition of ultrathin ionic liquid (UTIL) films with angle-resolved X-ray photoelectron spectroscopy (ARXPS), we demonstrate that by deposition of submonolayer amounts of Pd onto Au(111) the initial growth mode of the ionic liquid (IL) 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([C2C1Im][OTf]) can be switched from three-dimensional (3D) to two-dimensional (2D) gr...
متن کاملBiocatalysts Immobilized in Ultrathin Ordered Films
The immobilization of enzymes and other proteins into ordered thin materials has attracted considerable attention over the past few years. This research has demonstrated that biomolecules immobilized in different [Langmuir-Blodgett (LB)/Langmuir-Schaefer (LS)] matrixes retain their functional characteristics to a large extent. These new materials are of interest for applications as biosensors a...
متن کاملUltrathin, ordered oxide films on metal surfaces.
Metal oxides and oxide thin films are extensively used as active catalysts and catalytic supports, as well as in many other important technical applications. Unlike TiO(2), which is a semiconductor and can be investigated using a variety of surface science techniques, most metal oxides are insulators, which seriously restricts their use as model surfaces with modern surface science techniques. ...
متن کاملElectrochemical deposition of polypyrrole nanolayers on discontinuous ultrathin gold films.
Ultrathin layers of polypyrrole (PPy) were electrochemically grown between microelectrodes on a Si/SiO(2) substrate. Conducting nanolayers of PPy are directly grown onto ultrathin discontinuous gold (Au) film between the microelectrodes, with thicknesses in the range 10-100 nm. The system therefore forms a novel (PPy/Au) nanocomposite conductor. Atomic force microscopy (AFM) imaging and conduct...
متن کاملThe structure of ordered Au films on TiOx
The growth of Au on an ultra-thin, ordered Mo(112)–(8 · 2)-TiOx, was investigated using scanning tunneling microscopy (STM), low energy ion scattering spectroscopy (LEISS), X-ray photoelectron spectroscopy (XPS), and temperature programmed desorption (TPD). Wetting of the TiOx surface by Au was observed with STM and LEISS, and the ordering of the Au films was atomically resolved with STM. TPD s...
