Tanthauzo la LiAlO2 Substrate
Gawo laling'ono la LiAlO2 limatanthawuza gawo lapansi lopangidwa ndi lithiamu aluminium oxide (LiAlO2).LiAlO2 ndi gulu la crystalline la gulu la danga la R3m ndipo lili ndi mawonekedwe a kristalo atatu.
Magawo a LiAlO2 akhala akugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo kukula kwa filimu yopyapyala, zigawo za epitaxial, ndi ma heterostructures a zipangizo zamagetsi, optoelectronic, ndi photonic.Chifukwa champhamvu zake zakuthupi komanso zamankhwala, ndizoyenera kwambiri kupanga zida zambiri za bandgap semiconductor.
Chimodzi mwazofunikira kwambiri za magawo a LiAlO2 ndi pazida za Gallium Nitride (GaN) monga High Electron Mobility Transistors (HEMTs) ndi Light Emitting Diodes (LEDs).Kusagwirizana kwa lattice pakati pa LiAlO2 ndi GaN ndikocheperako, zomwe zimapangitsa kukhala gawo loyenera kukula kwamakanema owonda a GaN.Gawo laling'ono la LiAlO2 limapereka template yapamwamba kwambiri ya GaN deposition, zomwe zimapangitsa kuti chipangizochi chiziyenda bwino komanso kudalirika.
Magawo a LiAlO2 amagwiritsidwanso ntchito pazinthu zina monga kukula kwa zida za ferroelectric pazida zokumbukira, kupanga zida za piezoelectric, komanso kupanga mabatire olimba.Makhalidwe awo apadera, monga matenthedwe apamwamba, kukhazikika kwamakina, komanso kutsika kwa dielectric pafupipafupi, amawapatsa zabwino pamagwiritsidwe awa.
Mwachidule, gawo lapansi la LiAlO2 limatanthawuza gawo lapansi lopangidwa ndi lithiamu aluminium oxide.Magawo a LiAlO2 amagwiritsidwa ntchito pazinthu zosiyanasiyana, makamaka pakukula kwa zida za GaN, komanso kupanga zida zina zamagetsi, optoelectronic ndi photonic.Amakhala ndi zinthu zofunika zakuthupi ndi zamankhwala zomwe zimawapangitsa kukhala oyenera kuyika mafilimu opyapyala ndi ma heterostructures ndikuwongolera magwiridwe antchito a chipangizocho.
