What are thin films used for?
Thin films are used for protecting the surface of many material, especially optical elements, from wear, scratches, fingerprints, and even from corrosion.
Which type of technology is used in thin film?
Basically, most of the materials can be grown as thin-film form, and various thin film growth techniques have been applied, such as magnetron sputtering, pulsed laser deposition (PLD), Metal-organic Chemical Vapor Deposition (MOCVD), Molecular beam epitaxy (MBE) and so on.
What are the main applications of optical thin films?
Thin films are used to create optical coatings. Examples include low emissivity panes of glass for houses and cars, anti-reflective coatings on glasses, reflective baffles on car headlights, and for high precision optical filters and mirrors. Another application of these coatings is spatial filtering.
What are the thicknesses of typical thin films?
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness.
Where can thin films be found?
Thin film coatings has found applications in mirrors, microscopy, photo catalysis, photovoltaic, solar cells, switches, lenses, microelectronics, etc. Optical thin films involves the interaction of electromagnetic radiation, at different wavelengths, with a deposited functional layer.
Which of the following are methods used to deposit thin films?
In order to obtain thin films with good quality, there are two common deposition techniques: physical and chemical depositions. It can be summarized as shown in Table 1. Vacuum thermal evaporation. Electron beam evaporation.
How do you obtain thin film and what is the role of it?
This metal film can be produced by different methods such as physical vapor deposition (PVD); spray pyrolysis, sputtering, laser ablation, chemical vapor deposition (CVD); spin techniques, thermal evaporation, etc. Doping antimony sulfide with palladium helps to increase the application of antimony sulfide thin films.
How are thin films used as coating material?
Thin-film coatings play a prominent role on the manufacture of many electric devices. They are used to apply dopants and sealants to chips and other microelectronic parts. Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD) are two most common types of thin-film coating methods.
What are nanostructured thin films?
Nanostructured thin films containing metal or compound conductors are scientifically intriguing and technologically important. Their optical properties are linked to applications such as spectrally selective solar absorbers, solar control glazing, angular selective filters, optical biosensors and decorative paints.
