LiF Substrate Inkcazo
Iisubstrates ze-LiF (lithium fluoride) zibhekisa kwizinto ezisetyenziswa njengesiseko okanye inkxaso kwiinkqubo ezahlukeneyo zokubeka ifilim ebhityileyo kwimimandla ye-optics, photonics kunye ne-microelectronics.I-LiF yikristale ecacileyo kwaye ikhusela kakhulu kunye ne-bandgap ebanzi.
Ii-substrates ze-LiF ziqhele ukusetyenziswa kwizicelo zefilimu ezibhityileyo ngenxa yokungafihli kakuhle kwazo kwingingqi ye-ultraviolet (UV) kunye nokumelana okuphezulu nobushushu kunye neekhemikhali.Zifaneleke ngokukodwa usetyenziso olunje ngokutyabeka kwamehlo, ukubekwa kwefilimu ebhityileyo, i-spectroscopy kunye ne-electron microscopy.
Ii-substrates ze-LiF zihlala zikhethwa njengezixhobo ze-substrate ngenxa yokuba zine-absorption ephantsi kuluhlu lwe-UV kwaye zigudileyo ngokubonakalayo kwimilinganiselo echanekileyo kunye nechanekileyo okanye imigqaliselo.Ukongeza, i-LiF ibonisa uzinzo olufanelekileyo kumaqondo obushushu aphezulu kwaye inokumelana neendlela ezininzi zokubeka ezifana nokuphuma kwe-thermal, i-sputtering, kunye ne-molecular beam epitaxy.
Iipropathi ze-LiF substrates zibenza bafaneleke ngokukodwa usetyenziso kwi-UV optics, lithography, kunye ne-X-ray crystallography.Ukuchasana kwabo okuphezulu kwimiba yokusingqongileyo kunye nokuzinza kweekhemikhali kubenza babe zixhobo eziguquguqukayo zophando olwahlukeneyo kunye nokusetyenziswa kwemizi-mveliso.
Iimveliso ezinxulumeneyo
I-LiF (i-lithium fluoride) yaziwa ngokubanzi ngomgangatho wayo ogqwesileyo we-infrared (IR) njengesixhobo sokubona iifestile kunye neelensi.Nanga amanye amanqaku aphambili malunga neLiF2 iikristale zamehlo:
1. Ukukhanya kwe-infrared: I-LiF2 ibonisa ukucaca okugqwesileyo kwingingqi ye-infrared, ngakumbi kwi-infrared ephakathi kunye ne-far-infrared wavelengths.Iyakwazi ukuhambisa ukukhanya kuluhlu lwe-wavelength malunga ne-0.15 μm ukuya kwi-7 μm, iyenza ifaneleke kwiinkqubo ezahlukeneyo ze-infrared.
2. Ukufunxa okuphantsi: I-LiF2 ine-absorption ephantsi kwi-spectrum ye-infrared, ivumela ukuthotywa okuncinci kokukhanya kwe-infrared kwizinto eziphathekayo.Oku kuqinisekisa usulelo oluphezulu kwaye ngaloo ndlela usasazo olusebenzayo lwemitha ye-infrared.
3. Isalathisi esiphezulu se-refractive: I-LiF2 inesalathisi esiphezulu se-refractive kwi-infrared wavelength range.Le propati ivumela ulawulo olusebenzayo kunye nokuguqulwa kokukhanya kwe-infrared, iyenza ixabiseke kuyilo lwelensi olufuna ukugxila kunye nokugoba imitha ye-infrared.
4. I-Wide bandgap: I-LiF2 inomda obanzi malunga ne-12.6 eV, okuthetha ukuba ifuna igalelo lamandla aphezulu ukuqalisa iinguqu ze-elektroniki.Le propati inegalelo ekukhanyeni kwayo okuphezulu kunye nokufunxa okuphantsi kwi-ultraviolet kunye nemimandla ye-infrared.
5. Ukuzinza kwe-Thermal: I-LiF2 inozinzo oluhle lwe-thermal, eyenza ukuba ikwazi ukumelana nokushisa okuphezulu ngaphandle kokuthotywa kokusebenza okubalulekileyo.Oku kuyenza ifaneleke kwizicelo ezibandakanya ukuvezwa kumaqondo obushushu aphezulu, anje ngeenkqubo zokucinga nge-thermal okanye izinzwa ze-infrared.
6. Ukumelana nemichiza: I-LiF2 ichasene neekhemikhali ezininzi, kuquka i-acids kunye ne-alkali.Ayiphenduli okanye ithobe ngokulula phambi kwezi zinto, iqinisekisa ukuqina kwexesha elide kunye nokuthembeka kwee-optics ezenziwe kwi-LiF2.
7. I-Birefringence ephantsi: I-LiF2 ine-birefringence ephantsi, oku kuthetha ukuba ayikwahluli ukukhanya kwiindawo ezahlukeneyo ze-polarization.Le propati ibalulekile kwizicelo ezifuna ukuzimela kwe-polarization, njenge-interferometry okanye ezinye iinkqubo ezichanekileyo zokukhanya.
Ngokubanzi, i-LiF2 ithathwa kakhulu ngokusebenza kwayo kakuhle kwi-infrared spectrum, iyenza ibe yimathiriyeli exabisekileyo kwiifestile kunye neelensi kwiinkqubo ezahlukeneyo ze-infrared.Ukudityaniswa kwayo kokungafihlisi okuphezulu, ukufunxa okuphantsi, i-bandgap ebanzi, ukuzinza kwe-thermal, ukumelana neekhemikhali, kunye ne-birefringence ephantsi inegalelo ekusebenzeni kwayo okuhle kakhulu kwe-infrared.
