PMN-PT Ma'anar Substrate
PMN-PT substrate yana nufin fim na bakin ciki ko wafer da aka yi da kayan piezoelectric PMN-PT.Yana aiki azaman tushe mai goyan baya ko tushe don na'urorin lantarki daban-daban ko na optoelectronic.
A cikin mahallin PMN-PT, ma'auni yawanci shimfida ce mai tsayi wanda za'a iya girma ko adana siriri ko sifofi.PMN-PT substrates ana yawan amfani da su don ƙirƙira na'urori kamar na'urori masu auna firikwensin piezoelectric, actuators, transducers, da masu girbin makamashi.
Waɗannan ɓangarorin suna ba da tabbataccen dandamali don haɓaka ko sakawa na ƙarin yadudduka ko tsarin, ƙyale abubuwan piezoelectric na PMN-PT don haɗa su cikin na'urori.Sirin-fim ko wafer nau'i na PMN-PT substrates na iya ƙirƙirar ƙaƙƙarfan na'urori masu inganci waɗanda ke amfana daga ingantattun kaddarorin piezoelectric na kayan.

Babban ma'auni na lattice yana nufin daidaitawa ko daidaitawar sifofin lattice tsakanin abubuwa daban-daban guda biyu.A cikin mahallin MCT (mercury cadmium telluride) semiconductors, babban ma'auni na lattice yana da kyawawa saboda yana ba da damar haɓakar haɓaka mai inganci, ƙarancin lahani na epitaxial.
MCT abu ne mai haɗaɗɗiyar mahalli da aka saba amfani da shi a cikin injin gano infrared da na'urorin hoto.Don haɓaka aikin na'urar, yana da mahimmanci don haɓaka yadudduka na Epitaxial na MCT waɗanda suka yi daidai da tsarin lattice na kayan da ke ƙasa (yawanci CdZnTe ko GaAs).
Ta hanyar samun madaidaicin lattice mai girma, an inganta daidaituwar lu'u-lu'u tsakanin yadudduka, kuma an rage lahani da damuwa a wurin dubawa.Wannan yana haifar da ingantacciyar ingancin crystalline, ingantattun kayan lantarki da na gani, da ingantaccen aikin na'urar.
Babban daidaitawar lattice yana da mahimmanci ga aikace-aikace kamar hoton infrared da ji, inda ko da ƙananan lahani ko rashin lahani na iya lalata aikin na'urar, abubuwan da ke tasiri kamar hankali, ƙudurin sararin samaniya, da sigina-zuwa-amo rabo.
