I ke ola o kēlā me kēia lā, ua lilo nā mea uila e like me nā kelepona akamai a me nā uaki akamai i mau hoa pono ʻole. Ke lilo nei kēia mau mea i mea lahilahi a ʻoi aku ka ikaika. Ua noʻonoʻo paha ʻoe i ka mea e hiki ai i ko lākou ulu mau ʻana? Aia ka pane i nā mea semiconductor, a i kēia lā, ke nānā nei mākou i kekahi o nā mea koʻikoʻi loa i waena o lākou—he kristal sapphire.
ʻO ke aniani Sapphire, i haku nui ʻia me ka α-Al₂O₃, aia i ʻekolu mau ʻātoma oxygen a me ʻelua mau ʻātoma alumini i hoʻopaʻa ʻia me ke ʻano covalently, e hana ana i kahi ʻano hexagonal lattice. ʻOiai ua like ia me ka sapphire gem-grade i ke ʻano, ʻo nā kristal sapphire ʻoihana e hoʻokūpaʻa i ka hana maikaʻi loa. ʻAʻole i hoʻoheheʻe ʻia i ka wai ma ke ʻano kemika, ʻaʻole ia e hoʻoheheʻe ʻia i ka wai a kū i nā waikawa a me nā alkalis, e hana ana ma ke ʻano he "pale kemika" e mālama ana i ke kūpaʻa i nā wahi ʻino. Eia kekahi, hōʻike ia i ka transparency optical maikaʻi loa, e ʻae ana i ka hoʻoili mālamalama kūpono; conductivity thermal ikaika, e pale ana i ka wela nui; a me ka insulation uila maikaʻi loa, e hōʻoia ana i ka hoʻoili hōʻailona paʻa me ka ʻole o ka leakage. Ma ke ʻano mechanical, haʻaheo ka sapphire i ka paʻakikī Mohs o 9, ʻo ka lua wale nō i ka daimana, e hoʻolilo ana iā ia i mea pale loa i ke komo ʻana a me ka erosion - kūpono no nā noi koi.
ʻO ka mea kaua huna i ka hana ʻana i nā ʻāpana
(1) Mea Koʻikoʻi no nā ʻāpana mana haʻahaʻa
I ke ʻano o ke au uila i ka hoʻonui ʻia ʻana a me ka hana kiʻekiʻe, ua lilo nā ʻāpana mana haʻahaʻa i mea koʻikoʻi. Loaʻa nā ʻāpana kuʻuna i ka hōʻino ʻia o ka insulation ma nā mānoanoa nanoscale, e alakaʻi ana i ka leakage o ke au, ka hoʻonui ʻia o ka hoʻohana ʻana i ka mana, a me ka wela nui ʻana, kahi e hoʻopilikia ai i ke kūpaʻa a me ke ola.
Ua hoʻomohala nā kānaka noiʻi ma ka Shanghai Institute of Microsystem and Information Technology (SIMIT), Chinese Academy of Sciences, i nā wafers dielectric sapphire artificial me ka hoʻohana ʻana i ka ʻenehana oxidation intercalated metal, e hoʻololi ana i ka alumini kristal hoʻokahi i ka alumina kristal hoʻokahi (sapphire). Ma ka mānoanoa 1 nm, hōʻike kēia mea i ke au leakage haʻahaʻa loa, e ʻoi aku ana ma mua o nā dielectrics amorphous maʻamau ma o ʻelua mau kauoha o ka nui i ka hōʻemi ʻana o ka state density a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka interface me nā semiconductors 2D. ʻO ka hoʻohui ʻana i kēia me nā mea 2D e hiki ai i nā chips mana haʻahaʻa, e hoʻolōʻihi nui ana i ke ola pākaukau i nā kelepona akamai a hoʻonui i ka paʻa i nā noi AI a me IoT.
(2) ʻO ka hoa kūpono no Gallium Nitride (GaN)
Ma ke kahua semiconductor, ua puka mai ka gallium nitride (GaN) ma ke ʻano he hōkū ʻālohilohi ma muli o kona mau pono kūikawā. Ma ke ʻano he mea semiconductor ākea-bandgap me kahi bandgap o 3.4 eV—ʻoi aku ka nui ma mua o ka silicon 1.1 eV—ʻoi aku ka maikaʻi o GaN i nā noi wela kiʻekiʻe, voltage kiʻekiʻe, a me ke alapine kiʻekiʻe. ʻO kona neʻe ʻana o ka electron kiʻekiʻe a me ka ikaika o ke kahua haki koʻikoʻi e lilo ia i mea kūpono no nā mea uila mana kiʻekiʻe, mahana kiʻekiʻe, alapine kiʻekiʻe, a me ka ʻālohilohi kiʻekiʻe. I nā mea uila mana, hana nā mea hana GaN ma nā alapine kiʻekiʻe me ka hoʻohana ʻana i ka ikehu haʻahaʻa, e hāʻawi ana i ka hana maikaʻi loa i ka hoʻololi mana a me ka hoʻokele ikehu. I nā kamaʻilio microwave, hiki iā GaN ke hoʻohana i nā ʻāpana mana kiʻekiʻe, alapine kiʻekiʻe e like me nā amplifiers mana 5G, e hoʻonui ana i ka maikaʻi o ka hoʻoili hōʻailona a me ke kūpaʻa.
Ua manaʻo ʻia ʻo Sapphire crystal ʻo ia ka "hoa kūpono" no GaN. ʻOiai ʻoi aku ka kiʻekiʻe o kona lattice mismatch me GaN ma mua o ka silicon carbide (SiC), hōʻike nā substrates sapphire i ka thermal mismatch haʻahaʻa i ka wā o GaN epitaxy, e hāʻawi ana i kahi kahua paʻa no ka ulu ʻana o GaN. Eia kekahi, ʻo ka conductivity thermal maikaʻi loa o ka sapphire a me ka transparency optical e kōkua i ka hoʻoheheʻe wela maikaʻi ʻana i nā mea hana GaN mana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka paʻa o ka hana a me ka pono o ka hoʻopuka kukui maikaʻi loa. ʻO kona mau waiwai insulation uila kiʻekiʻe e hoʻemi hou aku i ka hoʻopilikia hōʻailona a me ka nalowale o ka mana. ʻO ka hui pū ʻana o ka sapphire a me GaN ua alakaʻi i ka hoʻomohala ʻana o nā mea hana kiʻekiʻe, me nā LED e pili ana iā GaN, ka mea e hoʻomalu ana i nā mākeke kukui a me ka hōʻike - mai nā kukui LED hale a i nā pale waho nui - a me nā diode laser i hoʻohana ʻia i nā kamaʻilio optical a me ka hana laser pololei.
