The surface morphology and microstructure of laser-ablated Pb~Zr0.52Ti0.48!O3 ~PZT! films on a ~100! SrTiO3 ~STO! substrate at early growth stage are characterized by means of atomic-force microscope, x-ray diffraction, and high-resolution transmission electron microscopy analysis. The ~100! STO surface is found to be very favorable for epitaxial growth of ~001! PZT films, which undergo a three...

We apply the classical over-the-barrier (COB) model to charge transfer between highly charged ions (HCIs) and targets consisting of thin dielectric films on metals. Distances for the onset of classically allowed above-surface electron capture are obtained as a function of HCI charge state, film thickness, film permittivity, and film-metal electron binding energies. The model describes the cross...

Experiments are performed to provide an insight into the heat transfer aspects of a wavy liquid film. Local film thickness and liquid temperature are measured simultaneously using a thermal conductance thickness probe and fast response thermocouples as the wavy film falls over an electrically heated wall. Liquid temperature at a fixed distance from the wall generally increases in the thin subst...

Nanoscale, vanadia-based, quasi-liquid films of self-selecting (equilibrium) thickness were observed on TiO2 surfaces in six ternary oxide systems (Ti–V–X–O; X = P, Na, K, Nb, Mo or W). It is demonstrated that the film appearance and thickness could be tailored via co-doping or changing the equilibration temperature. Furthermore, the observed discontinuous changes in film thickness, hysteresis ...

The influence of the film thickness and the substrate’s refractive index on the surface mode 7 at the superstrate is an important study step that may help clearing some of the misunderstandings 8 surrounding their propagation mechanism. A single sub-wavelength slit perforating a thin metallic 9 film is among the simplest nanostructure capable of launching Surface Plasmon Polaritons on its 10 su...

To ensure bearing reliability, it is traditional for compressor manufacturers to specify a minimum oil sump temperature difference above the saturated discharge temperature in a high-side compressor and suction temperature in a low-side compressor. This minimum oil sump temperature specification is, in essence, a surrogate measure of the minimum viscosity the compressor manufacturer reqtrires t...

A non-destruction evaluation of atomically thin hexagonal boron nitride (h-BN) films is critical to the U.S. Air Force and Department of Defense initiatives pursuing graphene-based electronic field effect transistors (FETs) capable of operating at terahertz frequencies. H-BN thin films an increase to the characteristic E2g 1367cm -1 h-BN peak intensity has been correlated to an increase in film...

A fully-coupled thermoelastic model for a fixed pad thrust bearing has been developed. Pressure, film thickness and three-dimensional temperature profiles were obtained by simultaneously solving the Reynolds, film thickness, energy and force balance equations using a combined finite difference and finite element method. The elastic deformation due to the pressure and the thermal distortion due ...

The plane-strain bulge test is used to investigate the mechanical behavior of freestanding electroplated Cu thin films as a function of film thickness and microstructure. The stiffness of the films increases slightly with decreasing film thickness because of changes in the crystallographic texture and the elastic anisotropy of Cu. Experimental stiffness values agree well with values derived fro...

One of the main approaches to increase thermoelectric figure merit materials is reduce their thermal conductivity and, in this respect, surface and possible interfaces play an important role low-dimensional structures. By means nonequilibrium molecular dynamics simulations at 300 K we investigate longitudinal phonon Si/Ge multilayered thin-film structures having sharp (100), (110), (111) crysta...
