LiAlO2 Pāpā

ʻO ka LiAlO2 substrate e pili ana i kahi pani i hana ʻia me ka lithium alumini oxide (LiAlO2).ʻO LiAlO2 kahi hui aniani o ka pūʻulu ākea R3m a he ʻano aniani ʻekolu kona.

Ua hoʻohana ʻia nā substrates LiAlO2 i nā ʻano noi like ʻole, me ka ulu ʻana o ke kiʻiʻoniʻoni lahilahi, nā papa epitaxial, a me nā heterostructures no nā mea uila, optoelectronic, a me photonic.Ma muli o kāna mau waiwai kino a me nā mea kemika, kūpono loa ia no ka hoʻomohala ʻana i nā mea hana semiconductor bandgap ākea.

ʻO kekahi o nā noi nui o nā substrates LiAlO2 aia ma ke kahua o nā mea hoʻokumu ʻia ʻo Gallium Nitride (GaN) e like me High Electron Mobility Transistors (HEMTs) a me nā Light Emitting Diodes (LED).He liʻiliʻi ka lattice mismatch ma waena o LiAlO2 a me GaN, e hoʻolilo iā ia i substrate kūpono no ka ulu epitaxial o nā kiʻi ʻoniʻoni lahilahi GaN.Hāʻawi ka substrate LiAlO2 i kahi hoʻohālike kiʻekiʻe no ka waiho ʻana o GaN, e hopena i ka hoʻomaikaʻi ʻana i ka hana a me ka hilinaʻi.

Hoʻohana pū ʻia nā substrates LiAlO2 ma nā kula ʻē aʻe e like me ka ulu ʻana o nā mea ferroelectric no nā mea hoʻomanaʻo, ka hoʻomohala ʻana i nā mea piezoelectric, a me ka hana ʻana i nā ʻōhua paʻa.ʻO kā lākou mau waiwai kūʻokoʻa, e like me ka conductivity thermal kiʻekiʻe, ke kūpaʻa mechanical maikaʻi, a me ka mau dielectric haʻahaʻa, hāʻawi iā lākou i nā pono i kēia mau noi.

I ka hōʻuluʻuluʻana, pili ka LiAlO2 substrate i kahi pani i hana ʻia me ka lithium alumini oxide.Hoʻohana ʻia nā substrates LiAlO2 i nā noi like ʻole, ʻoi aku ka nui o ka ulu ʻana o nā mea hoʻokumu ʻia ʻo GaN, a me ka hoʻomohala ʻana i nā mea uila, optoelectronic a me photonic.Loaʻa iā lākou nā waiwai kino a me nā kemika i kūpono iā lākou no ka waiho ʻana o nā kiʻiʻoniʻoni lahilahi a me nā heterostructure a hoʻomaikaʻi i ka hana o ka hāmeʻa.
