Mea semiconductor silikona carbide

Kalaka silika (SiC)ʻO ka mea semiconductor ka mea i oʻo loa i waena o nā semiconductors ākea ākea i hoʻomohala ʻia. Loaʻa i nā mea semiconductor SiC ka hiki ke hoʻohana nui i nā mea mahana kiʻekiʻe, alapine kiʻekiʻe, mana kiʻekiʻe, photoelectronics a me nā mea pale i ka radiation ma muli o ko lākou ākea ākea, kahua uila haki kiʻekiʻe, conductivity thermal kiʻekiʻe, ka neʻe ʻana o ka electron saturation kiʻekiʻe a me ka nui liʻiliʻi. Loaʻa iā Silicon carbide kahi ākea o nā noi: ma muli o kona ākea ākea, hiki ke hoʻohana ʻia e hana i nā diode kukui polū a i ʻole nā ​​​​mea ʻike ultraviolet i hoʻopilikia iki ʻia e ka lā; No ka mea hiki ke ʻae ʻia ke kahua uila a i ʻole ke kahua uila i ʻewalu mau manawa ma mua o ka silicon a i ʻole gallium arsenide, kūpono loa no ka hana ʻana i nā mea mana kiʻekiʻe-voltage e like me nā diode voltage kiʻekiʻe, ka triode mana, ka silicon controlled a me nā mea microwave mana kiʻekiʻe; Ma muli o ka wikiwiki o ka neʻe ʻana o ka electron saturation kiʻekiʻe, hiki ke hana ʻia i nā ʻano mea alapine kiʻekiʻe (RF a me microwave);Karbida silikaHe mea alakaʻi maikaʻi ia o ka wela a alakaʻi maikaʻi i ka wela ma mua o nā mea semiconductor ʻē aʻe, kahi e hana ai i nā mea silicon carbide i nā mahana kiʻekiʻe.

Ma ke ʻano he laʻana kikoʻī, ke hoʻomākaukau nei ʻo APEI e hoʻomohala i kāna ʻōnaehana hoʻokele motika DC kaiapuni koʻikoʻi no Venus Explorer (VISE) a NASA me ka hoʻohana ʻana i nā ʻāpana silicon carbide. Aia nō i ka pae hoʻolālā, ʻo ka pahuhopu ka hoʻopae ʻana i nā robots ʻimi ma luna o ka ʻili o Venus.

Eia kekahi, sʻilicon carbideLoaʻa iā ia kahi pilina covalent ionic ikaika, he paʻakikī kiʻekiʻe, conductivity thermal ma luna o ke keleawe, hana hoʻoheheʻe wela maikaʻi, kūpaʻa corrosion ikaika loa, kūpaʻa radiation, kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika maikaʻi a me nā waiwai ʻē aʻe, he ākea nā noi ma ke kahua o ka ʻenehana aerospace. No ka laʻana, ka hoʻohana ʻana i nā mea silicon carbide e hoʻomākaukau i nā mokulele no nā astronauts, nā mea noiʻi e noho a hana.
