What are the different types of thin film coatings?
Thin -layer coatings are made of dielectric, metal and oxide compounds that are commonly used in semiconductor industry, military and optical devices. Manufacturing processes usually include physical deposition of couples such as spray deposition or chemical deposition of couples where chemical reactions and plasma with high energy are used to store a film. Coatings classified as thin films are generally considered to be a maximum of one micron in thickness or 1,000 nanometers and can be pheromagnetic, ceramic or certain levels of conductive or insulating materials. Anti -reflective coatings are widely used in lenses found in cameras, binoculars and digital video players (DVDs) to reduce the normal reflection of light to reduce the performance of such a device. by reflective i aNtireflective features and television cameras. Reflective optical coatings are mirror and are usually made of aluminum, gold or silver, where they are used in photocopic machines, barcode scanners and industrial and military high -performance lasers.
Ceramic thin movies are used to coat tools for cutting exposed chemical and thermal stress, in the medical use of their inert properties and in many other areas. Lithium -ion batteries, which consist of ceramic thin film coatings, have been used in the electronic industry since 2011 and have been improved for over ten years of research in the Oak Ridge National Laboratory in the US. A ceramic base for integrated circuit is a platform for implanted batteries that can work in a wide temperature range, from -4 ° to 284 ° Fahrenheit (-20 ° to 140 ° C) and be any shape or size, andThis gives circuits wider applications than conventional construction. Their ability to operate at a temperature of up to 536 ° Fahrenheit (280 ° Celsius), if necessary, makes it useful for sensors, smart cards and implanted medical facilities such as defibrillators and nerve stimulation organs.
Thesolar cells of sensitized dyes (DSSC) also rely on the deposition of thin film titanium oxide, tio 2 , although they are usually 5 to 20 microns in thickness. This technology includes a combination of thin film coatings of ceramic, semiconductor and optical materials and is designed to endure sunlight for 20 years. Solid state proposals for the electronics of these solar cells offer promise that they are more cost -effective and simpler than standard solar cells based on silicon.
