  2. Thin-film equation - Wikipedia

    en.wikipedia.org/wiki/Thin-film_equation

    The basic form of a 2-dimensional thin film equation is [3] [4] [5] = where the fluid flux is = [(+ ^) + ^] +, and μ is the viscosity (or dynamic viscosity) of the liquid, h(x,y,t) is film thickness, γ is the interfacial tension between the liquid and the gas phase above it, is the liquid density and the surface shear.

  3. Sheet resistance - Wikipedia

    en.wikipedia.org/wiki/Sheet_resistance

    Resistor based on the sheet resistance of carbon film. Sheet resistance is the resistance of a square piece of a thin material with contacts made to two opposite sides of the square. [1] It is usually a measurement of electrical resistance of thin films that are uniform in thickness.

  4. Thin-film interference - Wikipedia

    en.wikipedia.org/wiki/Thin-film_interference

    The effects of thin-film interference can also be seen in oil slicks and soap bubbles. The reflectance spectrum of a thin-film features distinct oscillations and the extrema of the spectrum can be used to calculate the thickness of the thin-film. [1] Ellipsometry is a technique that is often used to measure properties of thin films. In a ...

  5. Slot-die coating - Wikipedia

    en.wikipedia.org/wiki/Slot-die_coating

    A photograph of a lab-scale slot-die coating tool for thin film materials research. Miniaturized slot-die tools have become increasingly available to support the development of new roll-to-roll compatible processes prior to the requirement of full pilot- and production-scale equipment. These tools feature similar core components and ...

    en.wikipedia.org/wiki/Refractive_index_and...

    Thickness of the Ge 40 Se 60 /Si film on the silicon substrate as 34.5 nm, Thickness of the Ge 40 Se 60 /Si film on the oxidized silicon substrate as 33.6 nm, Thickness of SiO 2 (with n and k spectra of SiO 2 held fixed), and; n and k spectra, in 190–1000 nm range, of Ge 40 Se 60 /Si.

  7. Thin film - Wikipedia

    en.wikipedia.org/wiki/Thin_film

    A thin film is a layer of materials ranging from fractions of a nanometer to several micrometers in thickness. [1] The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications.

  8. List of optics equations - Wikipedia

    en.wikipedia.org/wiki/List_of_optics_equations

    Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.

  9. Dynamic fluid film equations - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Fluid_Film_Equations

    Then the variable thickness of the film is captured by the two dimensional density . The dynamics of fluid films can be described by the following system of exact nonlinear Hamiltonian equations which, in that respect, are a complete analogue of Euler 's inviscid equations of fluid dynamics .
