ray reflectometry (surfaces, interfaces, films). PACS. 61.20.Gy -Theory and models of liquid structure. PACS. 61.20.Ne -Structure of simple liquids.Abstract. -Liquid octamethylcyclotetrasiloxane (OMCTS) films have been prepared between two flat silicon substrates with varying nanometer-sized gaps which correspond to two to three molecular diameters of OMCTS. These extremely confined liquid films have been investigated using X-ray scattering methods as a function of applied pressure, in particular by observing the specular reflectivity and the diffuse scattering. For the first time, scattering methods show that the gap size cannot be changed continuously with changing pressure. Instead, the gap is quantized due to ordering effects of the OMCTS molecules. The use of scattering methods has enormous future implications as they allow very detailed investigations of confined liquids at a molecular level.

Fabrication of 6,13-Bis(triisopropylsilylethynyl) Pentacene Films by Electrostatic Spray Deposition for Bottom-Contact Organic Field-Effect Transistors

“…The advantage of electrostatic spraying is that droplets can be extremely small. 14) The size of the disintegrated spray particles can range from 100 m down to several tens of nanometers, and the charge and size of the droplets can be controlled to some extent by electrical means, i.e., adjusting the voltage applied to the nozzle. 15) Compared to conventional spray deposition techniques, ESD has an advantage of high deposition efficiency (up to 80%) as the droplets are transported by electrical forces and does not need a carrier gas.…”
