Safaira e avea o se semiconductor so'oga eletise
O fasi safaira manifinifi o le fa'aoga manuia muamua lea o se mea e fa'a'ese'ese ai mea na tu'u ai le silikoni e fau ai ta'amilosaga tu'ufa'atasi e ta'ua o le silicon on sapphire (SOS).I le faaopoopo atu i lona tulaga sili ona lelei o le insulation eletise, o le safaira o loʻo i ai le maualuga o le vevela.
E fa'aaogaina fo'i fa'ama'i safaira tioata ta'itasi e fai ma sui i totonu o le alamanuia semiconductor mo le fa'atupuina o masini fa'avae gallium nitride (GaN).O le faʻaaogaina o le safaira e faʻaitiitia ai le tau e tusa ma le 1 / 7th le tau o le germanium.GaN i luga o le safaira e masani ona faʻaaogaina i diodes moli moli (LED).
Fa'aaoga e fai ma mea fa'amalama
O le safaira faʻapipiʻi (o nisi taimi e taʻua o le tioata safaira) e masani ona faʻaaogaina e fai ma mea faʻamalama aua e matua manino lava i le va o le 150 nm (ultraviolet) ma le 5500 nm (infrared) galu umi o le malamalama (o le fusi o loʻo vaʻaia mai le 380 nm i le 750 nm) ma e maualuga tele lona tete'e i le sasa.Fa'amanuiaga autu o fa'amalama safaira
Fa'aaofia
E matua'i lautele tele fa'asalalauga fa'asalalau fa'alava, mai le UV i le malamalama latalata-infrared
Malosi atu nai lo isi mea fa'apitoa po'o fa'amalama tioata
E maualuga le tete'e i le maosi ma abrasion (maaa minerale o le 9 i le fua Mohs, lona lua na'o taimane ma moissanite i mea masani)
maualuga tele le liusuavai (2030°C)
