Incazelo ye-LiF Substrate
Ama-substrates e-LiF (lithium fluoride) abhekisela ezintweni ezisetshenziswa njengesisekelo noma ukusekelwa kwezinqubo ezihlukahlukene zokubekwa kwefilimu emincane emikhakheni ye-optics, photonics kanye ne-microelectronics.I-LiF iyikristalu esobala futhi evikela kakhulu enebhande elibanzi.
Ama-substrates e-LiF avame ukusetshenziswa ekufakweni kwefilimu emincane ngenxa yokucaca kwawo okuhle kakhulu endaweni ye-ultraviolet (UV) kanye nokumelana okuphezulu nokushisa nokusabela kwamakhemikhali.Zifaneleka kakhulu izinhlelo zokusebenza ezinjengama-optical coatings, ukufakwa kwefilimu emincane, i-spectroscopy kanye ne-electron microscopy.
Ama-LiF substrates ngokuvamile akhethwa njengezisetshenziswa ze-substrate ngenxa yokuthi adonsa kancane ebangeni le-UV futhi abushelelezi ngokubonakalayo ukuze athole izilinganiso ezinembile nezinembayo noma ukubhekwa.Ngaphezu kwalokho, i-LiF ikhombisa ukuzinza okuhle emazingeni okushisa aphezulu futhi ingamelana namasu amaningi okubeka njengokuhwamuka okushisayo, i-sputtering, kanye ne-epitaxy ye-molecular beam.
Izici zama-substrates e-LiF ziwenza afanelekele ikakhulukazi ukusetshenziswa ku-UV optics, i-lithography, ne-X-ray crystallography.Ukumelana kwabo okuphezulu nezinto ezithinta imvelo nokuzinza kwamakhemikhali kubenza babe izinto eziguquguqukayo zocwaningo oluhlukahlukene kanye nezicelo zezimboni.
Imikhiqizo Ehlobene
I-LiF (i-lithium fluoride) yaziwa kabanzi ngezici zayo ezinhle kakhulu ze-infrared (IR) njengento ebonakalayo yamawindi namalensi.Nawa amanye amaphuzu abalulekile mayelana ne-LiF2 optical crystals:
1. Ukukhanya kwe-infrared: I-LiF2 ibonisa ukukhanyela okuhle kakhulu endaweni ye-infrared, ikakhulukazi phakathi kwe-infrared kanye namaza amaza akude.Ingakwazi ukudlulisa ukukhanya ebangeni lamaza acishe abe ngu-0.15 μm kuya ku-7 μm, iyenze ifaneleke ukusebenzela okunhlobonhlobo kwe-infrared.
2. Ukumuncwa okuphansi: I-LiF2 inokumunca okuphansi ku-spectrum ye-infrared, okuvumela ukuncishiswa okuncane kokukhanya kwe-infrared ngento.Lokhu kuqinisekisa ukudluliswa okuphezulu futhi ngaleyo ndlela ukudluliswa okuphumelelayo kwemisebe ye-infrared.
3. Inkomba ye-refractive ephezulu: I-LiF2 inenkomba ephezulu ye-refractive ebangeni le-infrared wavelength.Lesi sakhiwo sivumela ukulawula okusebenzayo kanye nokusetshenziswa kokukhanya kwe-infrared, okuyenza ibe wusizo kumadizayini amalensi adinga ukugxila futhi agobe imisebe ye-infrared.
4. I-Wide bandgap: I-LiF2 inebhande elibanzi cishe elingu-12.6 eV, okusho ukuthi idinga okokufaka kwamandla aphezulu ukuze kuqalwe izinguquko ze-elekthronikhi.Lesi sakhiwo sinomthelela ekukhanyeni kwayo okuphezulu kanye nokumuncwa okuphansi kwe-ultraviolet nezifunda ze-infrared.
5. Ukuzinza kwe-thermal: I-LiF2 inokusimama okuhle kwe-thermal, okuyenza ikwazi ukumelana namazinga okushisa aphezulu ngaphandle kokuwohloka kokusebenza okuphawulekayo.Lokhu kuyenza ifaneleke izinhlelo zokusebenza ezibandakanya ukuchayeka emazingeni okushisa aphezulu, njengamasistimu wokuthwebula izithombe ezishisayo noma izinzwa ze-infrared.
6. Ukumelana namakhemikhali: I-LiF2 imelana namakhemikhali amaningi, kuhlanganise nama-acids nama-alkali.Ayisabeli noma ilulaza kalula phambi kwalezi zinto, iqinisekisa ukuqina nokwethembeka kwesikhathi eside kwama-optics enziwe nge-LiF2.
7. I-Birefringence ephansi: I-LiF2 ine-birefringence ephansi, okusho ukuthi ayihlukanisi ukukhanya kuzimo ezihlukene ze-polarization.Lesi sakhiwo sibalulekile ezinhlelweni ezidinga ukuzimela kwe-polarization, njengaku-interferometry noma amanye amasistimu okubona ngokunemba.
Sekukonke, i-LiF2 ihlonishwa kakhulu ngokusebenza kwayo okuhle kakhulu kwi-infrared spectrum, okuyenza ibe yinto ebalulekile yamafasitela namalensi ezinhlobonhlobo zezinhlelo zokusebenza ze-infrared.Inhlanganisela yayo yokucaca okuphezulu, ukumuncwa okuphansi, i-bandgap ebanzi, ukuzinza okushisayo, ukumelana namakhemikhali, kanye ne-birefringence ephansi kunomthelela ekusebenzeni kwayo okuhle kakhulu kwe-infrared.
