ʻO ka mea Silicon carbide a me kona mau hiʻohiʻona

ʻO ka hāmeʻa semiconductor ke kumu o nā lako mīkini ʻoihana hou, i hoʻohana nui ʻia i nā kamepiula, nā mea uila mea kūʻai aku, nā kamaʻilio pūnaewele, nā mea uila kaʻa, a me nā wahi ʻē aʻe o ke kumu, ʻo ka ʻoihana semiconductor ka mea nui o nā ʻāpana kumu ʻehā: nā kaapuni hoʻohui, nā mea optoelectronic, nā mea discrete, a me nā sensor, ʻoi aku ma mua o 80% o nā kaapuni hoʻohui, a pinepine ka semiconductor a me ka kaapuni hoʻohui like.

E like me ke ʻano huahana, ua māhele nui ʻia ke kaapuni hoʻohui i ʻehā mau ʻāpana: microprocessor, hoʻomanaʻo, nā mea hana logic, nā ʻāpana simulator. Eia nō naʻe, me ka hoʻonui mau ʻana o ke kahua noi o nā mea semiconductor, he nui nā manawa kūikawā e pono ai nā semiconductors e pili i ka hoʻohana ʻana i ka mahana kiʻekiʻe, ka radiation ikaika, ka mana kiʻekiʻe a me nā wahi ʻē aʻe, mai hōʻino, ʻaʻohe mana o ka hanauna mua a me ka lua o nā mea semiconductor, no laila ua puka mai ka hanauna ʻekolu o nā mea semiconductor.

I kēia manawa, ʻo nā mea semiconductor band gap ākea i hōʻike ʻia ekalaka silicon(SiC), gallium nitride (GaN), zinc oxide (ZnO), daimana, alumini nitride (AlN) e noho ana i ka mākeke nui me nā pono nui aʻe, i kapa ʻia ʻo nā mea semiconductor hanauna ʻekolu. ʻO ke kolu o ka hanauna o nā mea semiconductor me ka laulā ākea o ka band gap, ʻoi aku ke kiʻekiʻe o ke kahua uila breakdown, thermal conductivity, electronic saturated rate a me ke kiʻekiʻe o ka hiki ke kūʻē i ka radiation, ʻoi aku ka kūpono no ka hana ʻana i nā mea wela kiʻekiʻe, alapine kiʻekiʻe, kūʻē i ka radiation a me nā mea mana kiʻekiʻe, i ʻike pinepine ʻia he mau mea semiconductor bandgap ākea (ʻoi aku ka laulā o ka band i pāpā ʻia ma mua o 2.2 eV), i kapa ʻia hoʻi he mahana kiʻekiʻe nā mea semiconductor. Mai ka noiʻi o kēia manawa ma nā mea semiconductor hanauna ʻekolu a me nā mea hana, ʻoi aku ka oʻo o nā mea silicon carbide a me gallium nitride semiconductor, aʻenehana silicon carbideʻo ia ka mea i oʻo loa, ʻoiai ke noiʻi ʻana ma ka zinc oxide, daimana, alumini nitride a me nā mea ʻē aʻe aia nō i ke kahua mua.

Nā Mea Hana a me ko lākou mau Waiwai：

Karbida silikaHoʻohana nui ʻia ka mea i nā bearings ball ceramic, valves, semiconductor materials, gyros, mea ana, aerospace a me nā mahina ʻē aʻe, ua lilo i mea hiki ʻole ke hoʻololi ʻia ma nā kahua ʻoihana he nui.

He ʻano superlattice kūlohelohe ʻo SiC a he polytype homogeneous maʻamau. Aia ma mua o 200 (i ʻike ʻia i kēia manawa) nā ʻohana polytypic homotypic ma muli o ka ʻokoʻa o ke kaʻina hoʻopili ma waena o nā papa diatomic Si a me C, kahi e alakaʻi ai i nā ʻano kristal like ʻole. No laila, kūpono loa ʻo SiC no ka hanauna hou o ka mea substrate diode emitting light (LED), nā mea uila mana kiʻekiʻe.
