Thin films Thin films A Langmuir-Blodgett film contains of one or more monolayers of an organic material, deposited from the surface of a liquid onto a solid by immersing (or emersing) the solid substrate into (or from) the liquid. A monolayer is added with each immersion or emersion step, thus films with very accurate thickness can be formed. ...more on Wikipedia about "Langmuir-Blodgett film"
A monolayer is a single, closely packed layer of atoms or molecules ** . A Langmuir monolayer is a one-molecule thick insoluble layer of an organic material spread onto an aqueous sub phase. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail. Since the 1980s a large number of other materials have been employed to produce Langmuir monolayers, some of which are semi-amphiphilic, including macromolecules such as polymers. Langmuir monolayers are extensively studied for the fabrication of Langmuir-Blodgett film (LB films), which are formed by transferred monolayers on a solid substrate. ...more on Wikipedia about "Monolayer"
Self assembled monolayers are surfaces consisting of a single layer of molecules on a substrate. Rather than having to use a technique such as chemical vapor deposition or molecular beam epitaxy to add molecules to a surface (often with poor control over the thickness of the molecular layer), self assembled monolayers can be prepared simply by adding a solution of the desired molecule onto the substrate surface and washing off the excess. ...more on Wikipedia about "Self-assembled monolayer"
Thin films are material layers of about 1 µm thickness. Electronic semiconductor devices and optical coatings are the main applications benefiting from thin film construction. Some work is being done with ferromagnetic thin films as well for use as computer memory. ...more on Wikipedia about "Thin film"
Thin film memory is a high-speed variation of core memory developed by Sperry Rand in a government-funded research project. ...more on Wikipedia about "Thin film memory"
Thin-film optics is the branch of optics which deals with very thin structured layers of different materials. In order to exhibit thin-film optics, the thickness of the layers of material must be on the order of the wavelengths of visible light (about 500 nm). Layers at this scale can have remarkable reflective properties due to light wave interference and the difference in refractive index between the layers, the air, and the substrate. These effects alter the way the optic reflects and transmits light. You can observe these effects every day in soap bubbles and oil slicks. ...more on Wikipedia about "Thin-film optics"
A thin film transistor (TFT) is a special kind of field effect transistor made by depositing thin films for the metallic contacts, semiconductor active layer, and dielectric layer. Anne Chiang, a Taiwanese-American, is credited with major advances in the development of TFT technology ** . ...more on Wikipedia about "Thin-film transistor"
