LiF Substrate Fa'amatalaga
LiF (lithium fluoride) substrates e faasino i mea o loʻo faʻaaogaina e fai ma faʻavae poʻo le lagolago mo le tele o faʻagasologa o le faʻapipiʻiina o ata manifinifi i matata o mata, photonics ma microelectronics.O le LiF o se tioata manino ma sili ona faʻafefeteina ma se vaeluaga lautele.
LiF substrates e masani ona faʻaaogaina i ata manifinifi talosaga ona o lo latou manino lelei i le ultraviolet (UV) itulagi ma maualuga teteʻe i le vevela ma gaioiga faʻamaʻi.E sili ona talafeagai mo faʻaoga e pei o faʻapipiʻi mata, faʻapipiʻi ata manifinifi, spectroscopy ma electron microscopy.
LiF substrates e masani lava ona filifilia e fai ma mea fa'apipi'i ona e maualalo le mitiia i le va o le UV ma e fa'alelei lelei mo le sa'o ma le sa'o o fua po'o le matauina.E le gata i lea, o le LiF o loʻo faʻaalia lelei le mautu i le maualuga o le vevela ma e mafai ona tatalia le tele o auala faʻapipiʻi e pei o le vevela vevela, sputtering, ma le molecular beam epitaxy.
O meatotino a le LiF substrates e fa'apitoa ai mo fa'aoga i mata'itusi UV, lithography, ma X-ray crystallography.O lo latou tetee maualuga i mea tau le siosiomaga ma le mautu o vailaʻau e faʻaogaina ai mea faʻapitoa mo suʻesuʻega eseese ma mea tau alamanuia.
Oloa Fa'atatau
O le LiF (lithium fluoride) e lauiloa tele ona o ana mea e sili ona lelei infrared (IR) o se mea faʻapipiʻi mo faamalama ma tioata.O nisi nei o manatu autu e uiga i tioata tioata LiF2:
1. Infrared transparency: LiF2 faʻaalia le manino lelei i totonu o le itulagi infrared, aemaise lava i le vaeluagalemu-infrared ma mamao-infrared wavelengths.E mafai ona tuʻuina atu le malamalama i le galu umi e tusa ma le 0.15 μm i le 7 μm, e faʻaogaina ai mo le tele o faʻaoga infrared.
2. Maualalo absorption: LiF2 e maualalo absorption i le alaleo infrared, faatagaina attenuation itiiti o le malamalama infrared e ala i mea.O lenei mea e mautinoa ai le maualuga o le felauaiga ma fa'apea lelei le tu'uina atu o fa'avevela infrared.
3. Fa'amaufa'ailoga maualuga: LiF2 o lo'o i ai se fa'asinomaga fa'asao maualuga i totonu o le umi o le galu infrared.O lenei meatotino e mafai ai ona pulea lelei ma faʻaogaina le malamalama infrared, ma faʻatauaina mo mamanu tioata e manaʻomia le taulaʻi ma punou le vevela infrared.
4. Fa'aupuga lautele: LiF2 o lo'o i ai se vaeluaga lautele e tusa ma le 12.6 eV, o lona uiga e mana'omia se fa'aoga maualuga malosi e amata ai suiga fa'aeletoroni.O lenei meatotino e saofagā i lona manino maualuga ma maualalo le faʻaogaina i le ultraviolet ma le infrared itulagi.
5. Faʻamautu vevela: LiF2 o loʻo i ai le faʻamautu lelei o le vevela, lea e mafai ai ona tatalia le maualuga o le vevela e aunoa ma le faʻaleagaina o galuega.O le mea lea e talafeagai ai mo talosaga e aofia ai le faʻaalia i le maualuga o le vevela, e pei o faiga faʻataʻitaʻiga vevela poʻo masini infrared.
6. Tete'e vaila'au: LiF2 e tetee i le tele o vaila'au, e aofia ai acids ma alkalis.E le fa'afoliga pe fa'aleaga gofie i le i ai o nei mea, fa'amautinoaina le tumau umi ma le fa'atuatuaina o mea mata na faia mai le LiF2.
7. Low birefringence: LiF2 e maualalo le birefringence, o lona uiga e le vaeluaina le malamalama i setete polarization eseese.O lenei meatotino e taua i talosaga e manaʻomia ai le tutoʻatasi polarization, e pei o le interferometry poʻo isi masini faʻapipiʻi saʻo.
I le aotelega, o le LiF2 e maualuga le fa'aaloalo ona o lona fa'atinoina lelei i le fusi o alaleo, ma avea ai ma mea taua mo fa'amalama ma tioata i le tele o fa'aoga infrared.O lona tu'ufa'atasiga o le maualuga o le manino, maualalo le absorption, lautele bandgap, fa'amautu vevela, fa'ama'i kemikolo, ma le maualalo birefringence fesoasoani i lona faatinoga lelei infrared.
