Substrate PMN-PT
Sharaxaada
PMN-PT crystal waxa lagu yaqaanaa isku xidhka isku xidhka elektiroonigga ah ee aadka u sarreeya, isku xidhka piezoelectric oo sarreeya, cadaadis sare iyo luminta dielectric hoose.

PMN-PT Qeexitaan Substrate-ka
Substrate PMN-PT waxaa loola jeedaa filim khafiif ah ama maraq laga sameeyay walxo piezoelectric PMN-PT.Waxay u adeegtaa sidii saldhig taageero ama aasaas u ah aaladaha kala duwan ee elektiroonigga ah ama optoelectronic.
Marka la eego PMN-PT, substrate caadi ahaan waa dusha adag oo lakabyo khafiif ah lagu kori karo ama lagu kaydin karo.Substrate-ka PMN-PT waxaa badanaa loo isticmaalaa in lagu sameeyo aaladaha sida dareemayaasha piezoelectric, actuators, transducers, iyo kuwa tamarta goosta.
Substrates-yadani waxay bixiyaan meel xasiloon oo loogu talagalay kobaca ama dejinta lakabyo dheeraad ah ama dhismayaal, taas oo u oggolaanaysa sifooyinka piezoelectric ee PMN-PT in lagu daro qalabka.Filim khafiif ah ama foom wafer ah oo substrates PMN-PT ah ayaa abuuri kara qalab is haysta oo hufan oo ka faa'iideysta walxaha piezoelectric ee wanaagsan.
Alaabooyinka La Xiriira
Isbarbardhigga dhejiska sare waxaa loola jeedaa isku-habaynta ama is-waafajinta qaab-dhismeedyada xarkaha ee u dhexeeya laba walxood oo kala duwan.Marka la eego macnaha guud ee MCT (mercury cadmium telluride) semiconductors, isbarbardhigga dhejiska sare waa mid la jecel yahay sababtoo ah waxay u oggolaaneysaa korriinka lakabyada epitaxial ee tayo sare leh oo aan cillad lahayn.
MCT waa walxo isku-dhafan oo isku-dhafan oo caadi ahaan loo isticmaalo aaladaha infrared iyo aaladaha sawir-qaadista.Si kor loogu qaado waxqabadka aaladda, waxaa muhiim ah in la koro lakabyada Epitaxial MCT kuwaas oo si dhow ula jaan qaadaya qaab dhismeedka shabagga hoose ee walxaha hoose (sida caadiga ah CdZnTe ama GaAs).
Marka la gaaro isbarbardhigga shabagga sare, isku-dheellitirka crystal ee u dhexeeya lakabyada waa la wanaajiyaa, iyo cilladaha iyo cadaadiska is-dhexgalka ayaa la yareeyaa.Tani waxay keenaysaa tayada crystalline ka wanaagsan, hagaajinta guryaha korantada iyo indhaha, iyo kor u qaadista waxqabadka qalabka.
Isbarbardhigga dhejiska sare wuxuu muhiim u yahay codsiyada sida sawirka infrared iyo dareenka, halkaas oo xitaa cilladaha yaryar ama cilladaha ay hoos u dhigi karaan waxqabadka qalabka, saameynaya arrimaha sida dareenka, xallinta booska, iyo saamiga calaamad-ilaa-qeylada.
