PMN-PT Substrate Txhais
PMN-PT substrate yog hais txog ib zaj duab xis nyias lossis wafer ua los ntawm cov khoom siv piezoelectric PMN-PT.Nws ua hauj lwm pab txhawb los yog lub hauv paus rau ntau yam khoom siv hluav taws xob lossis optoelectronic.
Nyob rau hauv cov ntsiab lus ntawm PMN-PT, ib qho substrate feem ntau yog ib qho chaw tiaj tiaj uas cov txheej nyias nyias lossis cov qauv tuaj yeem loj hlob lossis tso.PMN-PT substrates feem ntau yog siv los tsim cov khoom siv xws li piezoelectric sensors, actuators, transducers, thiab cov khoom siv hluav taws xob.
Cov substrates no muab lub platform ruaj khov rau kev loj hlob lossis kev tso tawm ntawm cov txheej txheem ntxiv lossis cov qauv, tso cai rau cov khoom siv piezoelectric ntawm PMN-PT ua ke rau hauv cov khoom siv.Nyias-zaj duab xis los yog wafer daim ntawv ntawm PMN-PT substrates tuaj yeem tsim cov khoom siv compact thiab ua tau zoo uas tau txais txiaj ntsig los ntawm cov khoom siv zoo heev piezoelectric zog.
Yam khoom
High lattice matching yog hais txog kev sib tw lossis kev sib txuam ntawm cov qauv lattice ntawm ob yam khoom sib txawv.Nyob rau hauv cov ntsiab lus ntawm MCT (mercury cadmium telluride) semiconductors, siab lattice matching yog xav tau vim nws tso cai rau kev loj hlob ntawm high-zoo, tsis xws luag-dawb epitaxial txheej.
MCT yog cov khoom siv semiconductor feem ntau siv hauv cov khoom siv hluav taws xob thiab cov duab kos duab.Txhawm rau ua kom cov cuab yeej ua tau zoo tshaj plaws, nws yog ib qho tseem ceeb kom loj hlob MCT epitaxial txheej uas zoo sib xws rau cov qauv lattice ntawm cov khoom siv hauv qab (feem ntau CdZnTe lossis GaAs).
Los ntawm kev ua tiav cov lattice siab sib txuam, cov siv lead ua kev sib raug zoo ntawm cov khaubncaws sab nraud povtseg tau txhim kho, thiab qhov tsis xws luag thiab lim ntawm qhov sib cuam tshuam raug txo.Qhov no ua rau kom zoo dua crystalline zoo, txhim kho hluav taws xob thiab kho qhov muag, thiab txhim kho cov cuab yeej ua haujlwm.
High lattice matching yog ib qho tseem ceeb rau cov ntawv thov xws li infrared imaging thiab sensing, qhov twg txawm me me los yog imperfections yuav degrade ntaus ntawv kev ua tau zoo, cuam tshuam rau yam xws li rhiab heev, spatial daws teeb meem, thiab teeb liab-rau-suab nrov piv.
