Which Device Involves The Use Of Plasma In Technology
Plasma, as an ionized gas, has wide applications in many cutting-edge technologies. This article explores some key devices that operate on the principles of plasma.
Inert gases are injected between two glass substrates and ionized into plasma through electric fields.
Plasma excites phosphors to emit different colors of light, forming images.
Compared to LCDs, plasma TVs have wider viewing angles and higher contrast.
High-frequency currents are introduced into argon plasma to convert electricity into heat that can cut metal.
High-temperature plasma melts and cuts steel, titanium alloys, and more.
Used extensively in industrial cutting, welding, and processing.
Plasma-Enhanced Chemical Vapor Deposition
Gaseous precursors are introduced in a reactor to form ionized plasma that excites and decomposes the molecules.
The deposited thin films have more uniform and dense structures.
Used to produce solar cells, composites, and advanced electronic devices.
Plasma technology has wide applications, from daily plasma TVs to advanced plasma-enhanced chemical vapor deposition. With technological advances, applied devices leveraging plasma will continue to emerge.
