Muraayad silicon ah oo dahaadhaysan oo silicon ah oo si gaar ah loogu dahaadhay filim ka-hortagga milicsiga AR

Muraayad silicon ah oo dahaadhaysan oo silicon monocrystalline ah oo si gaar ah loogu dahaadhay filim AR ah oo ka hortagga milicsiga Sawirka Featured

Sharaxaad Gaaban:

Muraayadaha silikoon ee monocrystalline ee dahaarka leh waa walxo indhaha ah oo shaqeynaya oo ku salaysan silikoon monocrystalline ah oo saafi ah (Si) iyadoo la adeegsanayo habka saxda ah ee farsamada indhaha iyo tignoolajiyada dahaarka. Silikoon monocrystalline wuxuu leeyahay gudbin iftiin oo aad u fiican oo ku jira xargaha infrared (1.2-7μm), marka lagu daro dahaarka sida filimka ka hortagga milicsiga (AR), filimka milicsiga sare (HR) ama filimka shaandhada, waxay si weyn u hagaajin kartaa waxqabadka gudbinta ama milicsiga ee xargaha gaarka ah. Badeecadaha waxaa si weyn loogu isticmaalaa sawir-qaadista infrared, indhaha laysarka iyo ogaanshaha semiconductor-ka.

Astaamaha

Astaamaha muraayadda silikoon ee dahaarka leh:

1. Waxqabadka indhaha:
Kala duwanaanshaha gudbinta: 1.2-7μm (oo u dhow infrared ilaa bartamaha infrared), gudbinta >90% ee xarigga daaqadda jawiga ee 3-5μm (ka dib marka la dahaadho).
Iyada oo ay ugu wacan tahay tusmada sare ee iftiinka (n≈ 3.4@4μm), filim ka hortagga milicsiga (sida MgF₂/Y₂O₃) waa in lagu dahaadhaa si loo yareeyo luminta milicsiga dusha sare.

2. Xasiloonida kulaylka:
Isugeynta ballaarinta kulaylka oo hooseysa (2.6×10⁻⁶/K), iska caabin heerkul sare (heerkulka shaqada ilaa 500℃), oo ku habboon codsiyada laysarka awoodda sare leh.

3. Sifooyinka farsamada:
Adkaanshaha Mohs 7, iska caabinta xoqidda, laakiin jilicsanaan badan, waxay u baahan tahay ilaalin ka hortagta xoqidda geesaha.

4. Astaamaha dahaarka:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.

Codsiyada muraayadaha silicon ee dahaarka leh:

(1) Nidaamka sawir-qaadista kulaylka infrared-ka
Qayb muhiim ah oo ka mid ah muraayadaha infrared-ka (3-5μm ama 8-12μm band) oo loogu talagalay la socodka amniga, kormeerka warshadaha iyo qalabka aragga habeenkii ee militariga.

(2) Nidaamka indhaha ee laysarka
Laser CO₂ (10.6μm): Muraayad iftiin sare leh oo loogu talagalay resonators-ka laysarka ama isteerinka iftiinka.

Laser-ka Fiber-ka (1.5-2μm): Muraayadaha filimka ka hortagga milicsiga waxay hagaajiyaan hufnaanta isku-xidhka.

(3) Qalabka tijaabinta Semiconductor-ka
Ujeedada mikroskoobka ee infrared-ka ee ogaanshaha cilladaha wafer-ka, oo u adkaysata daxalka plasma (ilaalinta dahaarka gaarka ah ayaa loo baahan yahay).

(4) qalabka falanqaynta muuqaalka
Iyada oo ah qayb ka mid ah spectral-ka Fourier infrared spectrometer (FTIR), gudbinta sare iyo qallooc hoose oo ku yimaada mowjadaha ayaa loo baahan yahay.

Xuduudaha farsamada:

Muraayadaha silikoon ee monocrystalline-ka ah ee dahaarka leh ayaa noqday qayb muhiim ah oo aan la beddeli karin oo ku jirta nidaamka indhaha ee infrared-ka sababtoo ah gudbinta iftiinka infrared-ka ee aadka u fiican, xasilloonida kulaylka sare iyo astaamaha dahaarka ee la beddeli karo. Adeegyadayada gaarka ah ee gaarka ah waxay hubiyaan waxqabadka ugu wanaagsan ee muraayadaha indhaha ee codsiyada laysarka, kormeerka iyo sawir-qaadista.

Adeegga gaarka ah ee XKH

XKH waxay bixisaa habayn dhammaystiran oo habka loo habeeyo muraayadaha silicon monocrystalline ee dahaarka leh: Laga bilaabo xulashada substrate silicon monocrystalline (iska caabinta >1000Ω·cm), habaynta indhaha ee saxda ah (goobaabin/isku-xidhnaan, saxnaanta dusha sare λ/4@633nm), dahaarka gaarka ah (ka-hortagga milicsiga/filimka milicsiga sare/shaandhada, taageerada naqshadaynta kooxaha badan), ilaa tijaabinta adag (heerka gudbinta, heerka dhaawaca laysarka, tijaabinta isku halaynta deegaanka), taageerada dufcad yar (10 xabbo) ilaa wax soo saar baaxad weyn. Waxay sidoo kale bixisaa dukumentiyo farsamo (qaloocyada dahaarka, xuduudaha indhaha) iyo taageerada iibka kadib si loo daboolo shuruudaha adag ee nidaamyada indhaha ee infrared.
