Safira sechikamu chedunhu re semiconductor
Mawafer esapphire matete ndiwo akatanga kushandiswa zvakanaka kwechinhu chinodzivirira kupisa (insulation substrate) chakaiswa silicon pairi kugadzira macircuit akabatanidzwa anonzi silicon on sapphire (SOS). Pamusoro pehunhu hwayo hwakanaka hwekudzivirira kupisa, sapphire ine simba rekupisa. Machipisi eCMOS pasapphire anonyanya kukodzera kushandiswa kwemafrequency eredhiyo ane simba guru (RF) akadai semafoni, maredhiyo ebhendi rekuchengetedza veruzhinji uye masisitimu ekutaurirana nesatellite.
Mawafer esapphire ega ekristaro anoshandiswawo sezvinhu zvinoshandiswa muindasitiri yesemiconductor pakurima michina yakagadzirwa negallium nitride (GaN). Kushandiswa kwesapphire kunoderedza mitengo zvakanyanya sezvo iri 1/7th yemutengo wegermanium. GaN pasapphire inowanzoshandiswa muma blue light emitting diodes (LEDs).
Shandisa sezvinhu zvepahwindo
Safira yakagadzirwa (dzimwe nguva inonzi girazi resafira) inowanzoshandiswa semahwindo nekuti inopenya zvikuru pakati pe150 nm (ultraviolet) ne5500 nm (infrared) wavelengths yechiedza (spectrum inooneka inotangira pa380 nm kusvika 750 nm) uye inodzivirira zvakanyanya kukwenya. Mabhenefiti makuru emahwindo esafira
Isawo
Bandwidth yakakura kwazvo yekutumira optical, kubva kuUV kusvika kuchiedza cheinfrared
Yakasimba kupfuura zvimwe zvinhu zvemaziso kana mahwindo egirazi
Inodzivirira zvikuru kukwenya nekukwenya (kuoma kwezvicherwa kwe9 pachikero cheMohs, iri yechipiri chete kudhaimani nemoissanite pakati pezvinhu zvakasikwa)
Nzvimbo yekunyunguduka yakanyanya (2030°C)
