LiAlO2 Substrate

LiAlO2 substrate yog hais txog lub substrate ua los ntawm lithium aluminium oxide (LiAlO2).LiAlO2 yog cov khoom siv crystalline uas muaj nyob rau hauv pawg R3m thiab muaj cov qauv duab peb sab.

LiAlO2 substrates tau siv ntau yam kev siv, suav nrog kev loj hlob ntawm zaj duab xis nyias, txheej txheej epitaxial, thiab heterostructures rau cov khoom siv hluav taws xob, optoelectronic, thiab photonic.Vim nws cov khoom zoo heev ntawm lub cev thiab tshuaj lom neeg, nws yog qhov tshwj xeeb tshaj yog tsim rau kev loj hlob ntawm cov khoom siv bandgap semiconductor.

Ib qho ntawm cov ntawv thov tseem ceeb ntawm LiAlO2 substrates yog nyob rau hauv thaj tsam ntawm Gallium Nitride (GaN) raws li cov khoom siv xws li High Electron Mobility Transistors (HEMTs) thiab Lub Teeb Emitting Diodes (LEDs).Lub lattice mismatch ntawm LiAlO2 thiab GaN yog qhov me me, ua rau nws tsim nyog substrate rau epitaxial loj hlob ntawm GaN nyias zaj duab xis.Lub LiAlO2 substrate muab cov qauv zoo rau GaN deposition, ua rau cov cuab yeej ua tau zoo dua thiab kev ntseeg tau.

LiAlO2 substrates kuj tseem siv rau hauv lwm qhov chaw xws li kev loj hlob ntawm ferroelectric cov ntaub ntawv rau cov khoom siv nco, kev tsim cov khoom siv piezoelectric, thiab kev tsim cov roj teeb hauv lub xeev.Lawv cov khoom tshwj xeeb, xws li thermal conductivity, zoo mechanical stability, thiab tsis tshua muaj dielectric tsis tu ncua, muab qhov zoo rau cov ntawv thov no.

Hauv cov ntsiab lus, LiAlO2 substrate yog hais txog lub substrate ua los ntawm lithium aluminium oxide.LiAlO2 substrates yog siv nyob rau hauv ntau yam kev siv, tshwj xeeb tshaj yog rau kev loj hlob ntawm GaN-raws li cov khoom siv, thiab kev loj hlob ntawm lwm yam khoom siv hluav taws xob, optoelectronic thiab photonic.Lawv muaj cov khoom tsim nyog lub cev thiab tshuaj lom neeg uas ua rau lawv tsim nyog rau kev tso tawm ntawm cov yeeb yaj kiab nyias thiab heterostructures thiab txhim kho cov cuab yeej ua haujlwm.
