Qeexida Substrate-ka LiF
Substrate-yada LiF (lithium fluoride) waxay tixraacaan agabka loo isticmaalo saldhigga ama taageerada hababka kala duwan ee dhigista filimada khafiifka ah ee dhinacyada optics, photonics iyo microelectronics.LiF waa crystal hufan oo aad u dahaaran oo leh faashad ballaadhan.
Substrate-ka LiF waxaa caadi ahaan loo isticmaalaa codsiyada filimada khafiifka ah sababtoo ah hufnaantooda aadka u fiican ee gobolka ultraviolet (UV) iyo iska caabbinta sare ee kuleylka iyo falcelinta kiimikada.Waxay si gaar ah ugu habboon yihiin codsiyada sida dahaarka indhaha, dhigista filimada khafiifka ah, spectroscopy iyo microscopy elektarooniga ah.
Substrate-yada LiF waxaa badanaa loo doortaa sida agabka substrate sababtoo ah waxay leeyihiin nuugista hoose ee kala duwanaanta UV waxayna si qumman u siman yihiin cabbirro sax ah oo sax ah ama indho-indheyn.Intaa waxaa dheer, LiF waxay soo bandhigtaa xasillooni wanaagsan heerkulka sare waxayna u adkeysan kartaa farsamooyin badan oo meel dhigis ah sida uumiga kulaylka, sputtering, iyo epitaxy molecular beam epitaxy.
Sifooyinka LiF substrates ayaa si gaar ah ugu habboon codsiyada UV optics, lithography, iyo crystallography X-ray.Iska caabbinta sare ee arrimaha deegaanka iyo xasiloonida kiimikada ayaa ka dhigaya agabyo badan oo cilmi baaris iyo codsiyo warshadeed oo kala duwan.
Alaabooyinka La Xiriira
LiF (lithium fluoride) waxaa si weyn loogu yaqaanaa infrared (IR) oo aad u wanaagsan sida walxaha indhaha ee daaqadaha iyo muraayadaha.Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan muraayadaha indhaha ee LiF2:
1. Hufnaanta Infrared: LiF2 waxay muujinaysaa hufnaan heersare ah oo ka jira gobolka infrared, gaar ahaan dhexda-infrared iyo hirarka fogaanta.Waxay gudbin kartaa iftiinka kala duwanaanshaha hirarka dhererka qiyaastii 0.15 μm ilaa 7 μm, taasoo ka dhigaysa mid ku habboon codsiyada kala duwan ee infrared.
2. Nuugista hoose: LiF2 waxay leedahay nuugista hoose ee spectrum infrared, taas oo u oggolaanaysa in yar oo iftiinka infrared ah iyada oo loo marayo walxaha.Tani waxay hubinaysaa gudbinta sare iyo sidaas si hufan u gudbinta shucaaca infrared.
3. Tusaha wax-soo-celinta sare: LiF2 waxay leedahay index refractive sare ee kala duwanaanshaha hirarka dhererka infrared.Gurigani wuxuu u oggolaanayaa in si hufan loo xakameeyo iyo wax ka beddelka iftiinka infrared, taasoo ka dhigaysa mid qiimo leh naqshadaha muraayadaha ee u baahan in diiradda la saaro oo la leexiyo shucaaca infrared.
4. Bandgap ballaaran: LiF2 waxay leedahay faashad ballaadhan oo qiyaastii 12.6 eV ah, taas oo macnaheedu yahay inay u baahan tahay tamar sare si loo bilaabo isbeddelka elektaroonigga ah.Hantidani waxay gacan ka geysataa hufnaanteeda sare iyo nuugista hoose ee gobollada ultraviolet iyo infrared.
5. Degganaanshaha kulaylka: LiF2 waxay leedahay xasillooni kuleyl oo wanaagsan, taas oo u oggolaanaysa inay u adkeysato heerkulka sare iyada oo aan hoos u dhicin waxqabadka muhiimka ah.Tani waxay ka dhigaysaa mid ku habboon codsiyada ku lug leh soo-gaadhista heer-kulka sare, sida hababka sawirka kulaylka ama dareemayaasha infrared.
6. Kiimikada caabbinta: LiF2 waxay u adkaysataa kiimikooyin badan, oo ay ku jiraan asiidh iyo alkalis.Si sahal ah ugama falcesho ama hoos uguma dhacayso joogitaanka walxahan, hubinta adkeysiga muddada dheer iyo isku halaynta muraayadaha laga sameeyay LiF2.
7. Birefringence hooseeya: LiF2 waxay leedahay birefringence hooseeya, taas oo macnaheedu yahay in aanu iftiinka u kala qaybin dawlado kala duwan.Hantidani waxay muhiim u tahay codsiyada u baahan madax-banaanida polarization, sida interferometry ama hababka kale ee indhaha ee saxda ah.
Guud ahaan, LiF2 waxaa si weyn loogu qaddariyaa waxqabadkeeda ugu wanaagsan ee spectrum infrared, taasoo ka dhigaysa shay qiimo leh daaqadaha iyo muraayadaha ee codsiyada kala duwan ee infrared.Isku-darka hufnaanta sare, nuugista hoose, bandgap ballaaran, xasilloonida kulaylka, caabbinta kiimikada, iyo birefringence hooseeya waxay gacan ka geysataa waxqabadkeeda infrared aadka u fiican.
