Thickness of the Flowing Superfluid Film [PDF]
Physical Review Letters, 1970 It has recently been shown experimentally that the thickness of a saturated helium film is independent of its state of superflow. We present a simple model in which the thickness of such a film is fixed by dynamical considerations at the gas-film interface, and the required balance of forces is then provided by relatively minor adjustments in the film ...

Nonlinear phase error analysis of equivalent thickness in a white-light spectral interferometer
Nanotechnology and Precision Engineering, 2019 A white light spectral interferometry based on a Linnik type system was established to accurately measure the thin film thickness through transparent medium. In practical work, the equivalent thickness of a beam splitter and the mismatch of the objective

Cobalt Oxide Diffusion Kinetics in Ultra-Thin Amorphous Carbon Films
Tribology Online, 2019 The diffusion of oxidized cobalt metal (CoOx) through a sputtered amorphous carbon film is investigated as a function of carbon film thickness and of temperature in dry air. A kinetic model is developed using the experimental data.

Equilibrium helium film in the thick-film limit [PDF]
Low Temperature Physics, 2003 There are still some open questions about how the thickness of a liquid or solid quantum film, such as liquid helium or solid hydrogen, develops in certain limits. One of these is the thick-film limit, i.e., the crossover from the thick film to the bulk.
