Substrate Sapphire
Sharaxaada
Sapphire (Al2O3) hal crystal waa walxo badan oo shaqo badan leh.Waxay leedahay iska caabin heerkul sare ah, kuleyl wanaagsan oo kuleyl ah, qallafsanaan sare, gudbinta infrared iyo xasilloonida kiimikada wanaagsan.Waxaa si weyn loogu isticmaalaa qaybo badan oo warshadaha, difaaca qaranka iyo cilmi-baarista sayniska (sida daaqada infrared heerkulka sare).Isla mar ahaantaana, sidoo kale waa nooc ka mid ah walxaha substrate-ka crystal-ka ah ee si ballaaran loo isticmaalo.Waa substrate-ka ugu horreeya ee buluugga, violet-ka, midabka cad ee iftiinka iftiinka (LED) iyo warshadaha buluuga ah ee leysarka (LD) (filimka gallium nitride wuxuu u baahan yahay inuu noqdo epitaxial substrate sapphire marka hore), sidoo kale waa awood sare oo muhiim ah. substrate filim.Marka lagu daro nidaamka Y, nidaamka La iyo filimaanta kale ee heerkulka sare leh, waxaa sidoo kale loo isticmaali karaa in lagu kobciyo filimada cusub ee MgB2 (magnesium diboride) superconducting films (sida caadiga ah substrate-ka-crystal wuxuu noqon doonaa kiimiko ahaan daxaloobay inta lagu jiro soo saarista MgB2). filimada).

Qeexitaan Substrate Sapphire
Substrate Sapphire waxa loola jeedaa walxo crystalline hufan oo ka samaysan hal oksaydh crystal aluminium (Al2O3).Ereyga "sapphire" waxaa badanaa loo isticmaalaa in lagu qeexo noocyada kala duwan ee dhagaxa corundum, kaas oo inta badan midab buluug ah leh.Si kastaba ha ahaatee, marka la eego substrates, sapphire waxaa loola jeedaa ka samaysan macmal ah, midab lahayn, crystal nadiif ah oo loo isticmaalo codsiyada kala duwan.Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan sapphire substrates:
1. Qaab dhismeedka Crystal: Sapphire waxa ay leedahay qaab dhismeed laba geesood ah kaas oo atamka aluminium iyo atamka ogsijiinta si isdaba joog ah loo habeeyo.Waxay ka tirsan tahay nidaamka crystal trigonal.
2. Qalafsanaanta sare: Sapphire waa mid ka mid ah qalabka ugu adag ee loo yaqaan, oo leh Mohs adag oo ah 9. Tani waxay ka dhigaysaa mid aad u xoqan oo u adkaysta, ka qaybqaata adkaysigeeda iyo cimri dhererka codsiga.
3. Gudbinta iftiinka: Sapphire waxay leedahay gudbinta iftiinka aad u fiican, gaar ahaan meelaha la arki karo iyo kuwa u dhow-infrared.Waxay u gudbin kartaa iftiinka qiyaastii 180 nm ilaa 5500 nm, taas oo ka dhigaysa mid ku habboon codsiyada badan ee indhaha iyo indhaha.
4. Kuleylka iyo qalabka farsamada: Sapphire waxay leedahay kuleyl wanaagsan iyo sifooyin farsamo, barta dhalaalaysa sare, kororka fidinta kulaylka hoose, iyo habdhaqanka kulaylka aad u fiican.Waxay u adkeysan kartaa heerkulka sare, cadaadiska farsamada iyo kulaylka baaskiilka, taas oo ka dhigaysa mid ku habboon heerkulka sare iyo codsiyada awoodda sare.
5. Degganaanshaha kiimikaad: Sapphire waxa ay leedahay xasillooni kiimikaad oo sareysa waxayna iska caabin kartaa inta badan asiidhka, alkalis iyo dareerayaasha organic.Habkaani wuxuu hubinayaa cimrigiisa iyo isku halaynta jawiga adag ee kala duwan.
6. Qalabka dahaarka korantada: Sapphire waa dahaye koronto oo aad u fiican, kaas oo faa'iido u leh codsiyada u baahan go'doominta korantada.
7. Codsiga: Substrates Sapphire waxaa si weyn loogu isticmaalaa optoelectronics, semiconductors, diodes iftiin-bixiya, diodes laser, daaqadaha indhaha, daawashada kiristaalo iyo cilmi-baarista sayniska.
Substrates Sapphire ayaa aad loogu qiimeeyaa isku dhafka indhaha, farsamada, kulaylka iyo sifooyinka kiimikada.Alaabta aadka u wanaagsan ayaa ka dhigaysa mid ku haboon codsiyada u baahan adkeysiga sare, hufnaanta indhaha sare, dahaarka korantada iyo iska caabinta walxaha deegaanka.
