ʻO nā mea semiconductor silikon carbide

Silika kalapona (SiC)ʻO nā mea semiconductor ka mea ʻoi loa i waena o nā semiconductors ākea ākea i kūkulu ʻia. Loaʻa i nā mea semiconductor SiC ka hiki ke hoʻohana nui i ka wela kiʻekiʻe, ke alapine kiʻekiʻe, ka mana kiʻekiʻe, photoelectronics a me nā mea pale radiation ma muli o ko lākou ākea ākea, kiʻekiʻe haʻihaʻi uila, kiʻekiʻe thermal conductivity, kiʻekiʻe saturation electron mobility a me ka liʻiliʻi liʻiliʻi. ʻO ka Silicon carbide ka nui o nā noi: ma muli o kona ākea ākea, hiki ke hoʻohana ʻia e hana i nā diodes kukui polū a i ʻole nā ​​​​mea ʻike ultraviolet i pili ʻole i ka lā; No ka mea hiki ke ʻae ʻia ka volta a i ʻole ke kahua uila i ʻewalu mau manawa ma mua o ke silika a i ʻole gallium arsenide, ʻoi aku ka maikaʻi no ka hana ʻana i nā mea mana kiʻekiʻe-voltage e like me nā diodes kiʻekiʻe-voltage, power triode, silicon controlled and high-power microwave device; Ma muli o ke kiʻekiʻe o ka saturation electron migration wikiwiki, hiki ke hana ʻia i loko o nā ʻano mea like ʻole (RF a me ka microwave);Silicon carbideHe mea lawe maikaʻi i ka wela a hoʻokele i ka wela ma mua o nā mea semiconductor ʻē aʻe, e hana ana nā mea hana silicon carbide i nā wela kiʻekiʻe.

Ma ke ʻano he laʻana kikoʻī, ke mākaukau nei ʻo APEI e hoʻomohala i kāna ʻōnaehana kaʻa kaʻa DC kaiapuni no NASA's Venus Explorer (VISE) me ka hoʻohana ʻana i nā ʻāpana carbide silicon. Aia nō i ka papa hoʻolālā, ʻo ka pahuhopu ka pae ʻana i nā robots ʻimi ma ka ʻili o Venus.

Eia hou, silicon carbideLoaʻa iā ia kahi paʻa ionic covalent ikaika, he kiʻekiʻe ka paʻakikī, thermal conductivity ma luna o ke keleawe, maikaʻi ka wela dissipation hana, corrosion kūpaʻa ikaika loa, radiation kū'ē, kiʻekiʻe wela kū'ē a me ka maikaʻi kemika paʻa a me nā waiwai 'ē aʻe, he laulā o nā noi i loko o ka kahua o ka ʻenehana aerospace. No ka laʻana, ka hoʻohana ʻana i nā mea carbide silicon no ka hoʻomākaukau ʻana i nā mokulele no nā astronauts, nā mea noiʻi e noho a hana.
