Abstract

Fluoride plasma treatment similar to that used in AlGaN/GaN HEMTs has been applied to InAlN/GaN HEMTs. Enhancement mode of operation is obtained with a pinch-off voltage shifted by 3 V. Owing to the fluoride treatment an increase of the forward gate threshold to 3.5 V is observed. The small-signal performances are essentially unchanged. The thermal stability of this process has been assessed for the first time and appears to be limited to approximately 500 degrees C.

Fluoride therapy

Fluoride therapy is the use of fluoride for medical purposes. Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. It is typically used as a liquid, pill, or paste by mouth. Fluoride has also been used to treat a number of bone diseases. Relatively high ingestion of fluoride by babies and children may result in white marks on the teeth known as fluorosis.

Fluoride

Fluoride (ˈflʊəraɪd,_ˈflɔr-) is an inorganic, monatomic anion of fluorine, with the chemical formula F− (also written [F]−), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin.

Water fluoridation

Water fluoridation is the controlled adjustment of fluoride to a public water supply solely to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities.
