LiF Substrate Tlhaloso
Li-substrates tsa LiF (lithium fluoride) li bua ka lisebelisoa tse sebelisoang e le motheo kapa ts'ehetso bakeng sa lits'ebetso tse fapaneng tse tšesaane tsa ho beha lifilimi libakeng tsa optics, photonics le microelectronics.LiF ke kristale e bonaletsang le e sireletsang haholo e nang le lekhalo le pharaletseng.
Li-substrates tsa LiF li atisa ho sebelisoa lits'ebetsong tse tšesaane tsa filimi ka lebaka la ponahalo ea tsona e ntle haholo sebakeng sa ultraviolet (UV) le ho hanyetsa mocheso le lik'hemik'hale tse phahameng.Li loketse ka ho khetheha lits'ebetsong tse kang liphahlo tsa optical, deposition e tšesaane ea filimi, spectroscopy le microscope ea elektronike.
Li-substrates tsa LiF hangata li khethoa e le lisebelisoa tsa substrate hobane li na le monyetla o tlase sebakeng sa UV 'me li boreleli bakeng sa litekanyo tse nepahetseng le tse nepahetseng kapa tse shebiloeng.Ntle le moo, LiF e bonts'a botsitso bo botle mochesong o phahameng mme e khona ho mamella mekhoa e mengata ea ho beha lintho joalo ka mouoane oa mocheso, ho phatloha, le epitaxy ea molek'hule.
Thepa ea li-substrates tsa LiF e li etsa hore li tšoanelehe haholo bakeng sa ts'ebeliso ho UV optics, lithography, le X-ray crystallography.Ho hanyetsa ha bona maemo a tikoloho le botsitso ba lik'hemik'hale ho ba etsa lisebelisoa tse fapaneng bakeng sa lipatlisiso tse fapaneng le lits'ebetso tsa indasteri.
Lihlahisoa tse Amanang
LiF (lithium fluoride) e tsebahala haholo ka thepa ea eona e ntle ka ho fetisisa ea infrared (IR) e le sesebelisoa sa mahlo bakeng sa lifensetere le lilense.Mona ke lintlha tsa bohlokoa mabapi le likristale tsa optical tsa LiF2:
1. Ponaletso ea infrared: LiF2 e bonts'a ponaletso e babatsehang sebakeng sa infrared, haholo-holo bohareng ba infrared le far-infrared wavelengths.E ka fetisa khanya ka bolelele ba maqhubu a ka bang 0.15 μm ho isa ho 7 μm, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse fapaneng tsa infrared.
2. Monyetla o tlase: LiF2 e na le ho monya ho tlase ho mabone a infrared, e lumellang ho fokotsoa ho fokolang ha leseli la infrared ka thepa.Sena se netefatsa phetiso e phahameng mme kahoo phetiso e sebetsang ea mahlaseli a infrared.
3. High refractive index: LiF2 e na le index e phahameng ea refractive ka har'a leqhubu la infrared wavelength.Thepa ena e lumella taolo e sebetsang hantle le ho qhekella ha leseli la infrared, e etsa hore e be ea bohlokoa bakeng sa meralo ea lense e hlokang ho tsepamisa le ho koba mahlaseli a infrared.
4. Wide bandgap: LiF2 e na le sehlopha se pharaletseng se ka bang 12.6 eV, e bolelang hore e hloka matla a mangata a matla ho qala liphetoho tsa elektronike.Thepa ena e kenya letsoho ponaletsong ea eona e phahameng le ho monya ho tlase libakeng tsa ultraviolet le infrared.
5. Thermal botsitso: LiF2 e na le botsitso bo botle ba mocheso, e leng se nolofalletsang ho mamella mocheso o phahameng ntle le ho senyeha ho hoholo ha ts'ebetso.Sena se etsa hore e tšoanelehe bakeng sa lits'ebetso tse kenyelletsang ho pepesehela mocheso o phahameng, joalo ka lisebelisoa tsa litšoantšo tsa mocheso kapa lisensara tsa infrared.
6. Ho hanyetsa lik'hemik'hale: LiF2 e hanyetsa lik'hemik'hale tse ngata, ho akarelletsa le acid le alkalis.Ha e sebetse kapa e theola habonolo ka pel'a lintho tsena, ho netefatsa ho tšoarella ha nako e telele le ho tšepahala ha li-optics tse entsoeng ho tloha LiF2.
7. Low birefringence: LiF2 e na le birefringence e tlaase, e bolelang hore ha e arole leseli libakeng tse fapaneng tsa polarization.Thepa ena e bohlokoa lits'ebetsong tse hlokang boikemelo ba polarization, joalo ka interferometry kapa lisebelisoa tse ling tse nepahetseng tsa optical.
Ka kakaretso, LiF2 e nkoa e le ea bohlokoa haholo ka lebaka la ts'ebetso ea eona e ntle ka ho fetisisa ho infrared spectrum, e etsang hore e be thepa ea bohlokoa bakeng sa lifensetere le lilense mefuteng e fapaneng ea lisebelisoa tsa infrared.Motsoako oa eona oa ponaletso e phahameng, ho monyela ho tlase, sekhahla se pharaletseng, botsitso ba mocheso, khanyetso ea lik'hemik'hale, le birefringence e tlase e kenya letsoho ts'ebetsong ea eona e ntle ea infrared.
