Katundu wakuthupi | C axis ili ndi kuwala kwa kristalo, ndipo nkhwangwa zina zimakhala ndi kuwala koyipa. Ndege C ndi yosalala, makamaka yodulidwa. | R-ndege yolimba pang'ono kuposa A. | M ndege imapondedwa mozungulira, yosavuta kudula, yosavuta kudula. | Kuuma kwa A-ndege ndikwambiri kuposa kwa C-ndege, yomwe imawonetseredwa mu kukana kuvala, kukana zikande ndi kuuma kwakukulu; Mbali ya A-ndege ndi ndege ya zigzag, yomwe ndi yosavuta kudula; | ||
Mapulogalamu | Magawo a safiro a C-oriented amagwiritsidwa ntchito kukulitsa mafilimu osungidwa a III-V ndi II-VI, monga gallium nitride, omwe amatha kupanga zinthu zamtundu wa blue LED, laser diode, ndi infrared detector applications. | Kukula kwa gawo lapansi loyang'ana pa R kwamitundu yosiyanasiyana ya silicon extrasystals, yomwe imagwiritsidwa ntchito m'mabwalo ophatikizika a ma microelectronics. | Amagwiritsidwa ntchito makamaka kukulitsa mafilimu osakhala a polar/semi-polar GaN epitaxial kuti apititse patsogolo kuwala kowala. | A-wokhazikika ku gawo lapansi amapanga chilolezo chofanana / chapakati, ndipo kutsekemera kwakukulu kumagwiritsidwa ntchito muukadaulo wa hybrid microelectronics. Ma superconductors otentha amatha kupangidwa kuchokera ku A-base elongated crystals. | ||
Processing mphamvu | Chitsanzo Sapphire Substrate (PSS) : Mumawonekedwe a Kukula kapena Etching, ma nanoscale enieni okhazikika ang'onoang'ono amapangidwa ndikupangidwa pagawo la safiro kuti azitha kuwongolera mawonekedwe a kuwala kwa LED, ndikuchepetsa kuwonongeka kwa kusiyana pakati pa GaN yomwe ikukula pamtengo wa safiro. , sinthani mtundu wa epitaxy, ndikuwonjezera mphamvu yamkati ya LED ndikuwonjezera mphamvu yakuchotsa kuwala. Komanso, safiro prism, galasi, mandala, dzenje, chulucho ndi mbali zina structural akhoza makonda malinga ndi zofuna za makasitomala. | |||||
