ʻO ka waʻa kristal Silicon carbide: ka mea kaua hou o ka ʻoihana semiconductor

Me ka holomua mau o ka ʻepekema a me ka ʻenehana, ke piʻi nei ka koi no nā mea hana kiʻekiʻe a me ka pono o ka ʻoihana semiconductor. Ma kēia kahua,waʻa kristal silicon carbideua lilo ia i mea nui o ka nānā ʻana no kona mau ʻano kūikawā a me nā kahua noi ākea. E hoʻolauna kēia pepa i nā pono a me nā noi o nā waʻa kristal silicon carbide i ka ʻoihana semiconductor, a hōʻike i kāna kuleana koʻikoʻi i ka hoʻolaha ʻana i ka hoʻomohala ʻana o ka ʻenehana semiconductor.

Nā Pōmaikaʻi:

1.1 Nā ʻano mahana kiʻekiʻe:

Waʻa kristal silicon carbideLoaʻa iā ia ke kūpaʻa wela kiʻekiʻe maikaʻi loa a me ka conductivity wela, hiki ke hana i kahi mahana kiʻekiʻe, a hiki ke kū i ka mahana hana ma mua o ka mahana o ka lumi. Hāʻawi kēia i nā waʻa SIC i kahi pono kūikawā i nā noi mana kiʻekiʻe a me nā mahana kiʻekiʻe, e like me nā uila mana, nā kaʻa uila a me ka aerospace.

1.2 Ka neʻe ʻana o ka electron kiʻekiʻe:

ʻOi aku ke kiʻekiʻe o ka neʻe ʻana o ka electron o nā waʻa kristal silicon carbide ma mua o nā mea silicon kuʻuna, ʻo ia hoʻi hiki iā ia ke hoʻokō i ka nui o ke au a me ka hoʻohana ʻana i ka mana haʻahaʻa. ʻO kēia ka mea e loaʻa ai i ka waʻa kristal silicon carbide kahi mana ākea ākea ma ke kahua o nā lako uila alapine kiʻekiʻe, mana kiʻekiʻe a me ke kamaʻilio alapine lekiō.

1.3 Ke kū'ē'ē ki'eki'e o ka radiation:

He kūpaʻa ikaika ka waʻa kristal silicon carbide i ka radiation a hiki ke hana paʻa i kahi kaiapuni radiation no ka manawa lōʻihi. ʻO kēia ka mea e lilo ai nā waʻa SIC i mea pono i nā ʻāpana nukelea, aerospace a me ka pale kaua, kahi e hāʻawi ai lākou i nā hopena hilinaʻi loa a lōʻihi ke ola.

1.4 Nā ʻano hoʻololi wikiwiki:

Ma muli o ka neʻe ʻana o ka electron a me ke kū'ē haʻahaʻa o ka waʻa kristal silicon carbide, hiki iā ia ke hoʻokō i ka wikiwiki hoʻololi wikiwiki a me ka pohō hoʻololi haʻahaʻa. ʻO kēia ka mea e lilo ai ka waʻa silicon carbide i mea maikaʻi nui i nā mea hoʻololi uila mana, nā ʻōnaehana hoʻoili mana a me nā ʻōnaehana hoʻokele, hiki ke hoʻomaikaʻi i ka pono o ka ikehu a hōʻemi i ka pohō ikehu.

Nā noi:

2.1 Nā mea uila mana kiʻekiʻe:

nā waʻa kristal silicon carbidehe ākea nā manaʻolana noi i nā noi mana kiʻekiʻe, e like me nā inverters no nā kaʻa uila, nā ʻōnaehana hana mana solar, nā mea hoʻokele kaʻa ʻoihana, a me nā mea ʻē aʻe. ʻO ko lākou kūpaʻa wela kiʻekiʻe a me ka neʻe ʻana o ka electron kiʻekiʻe e ʻae i kēia mau mea hana e hoʻokō i ka pono nui a me nā nui liʻiliʻi.

2.2 Mea hoʻonui mana RF:

ʻO ke kiʻekiʻe o ka neʻe ʻana o ka electron a me nā ʻano pohō haʻahaʻa o nā waʻa kristal silicon carbide e hoʻolilo iā lākou i mau mea kūpono no nā mea hoʻonui mana RF. Hiki i nā mea hoʻonui mana i nā ʻōnaehana kamaʻilio RF, nā radar a me nā lako lekiō ke hoʻomaikaʻi i ka nui o ka mana a me ka hana ʻōnaehana ma o ka hoʻohana ʻana i nā waʻa kristal silicon carbide.

2.3 Nā mea hana optoelectronic:

Hoʻohana nui ʻia nā waʻa kristal silicon carbide ma ke kahua o nā mea optoelectronic. Ma muli o kona kūpaʻa kiʻekiʻe i ka radiation a me ke kūpaʻa wela kiʻekiʻe, hiki ke hoʻohana ʻia nā waʻa kristal silicon carbide i nā diode laser, nā photodetectors a me nā kamaʻilio fiber optic, e hāʻawi ana i nā hopena hilinaʻi a me ka pono.

 

2.4 Nā mea uila wela kiʻekiʻe:

ʻO ke kūpaʻa kiʻekiʻe o ka mahana o ka waʻa kristal silicon carbide e hoʻohana nui ʻia ai i nā mea uila ma kahi mahana kiʻekiʻe. No ka laʻana, ka nānā ʻana i ka reactor nukelea ma ka ʻāpana ikehu nukelea, nā mea ʻike mahana kiʻekiʻe a me nā ʻōnaehana hoʻomalu mīkini ma ka ʻāpana aerospace.

 

Ma ka hōʻuluʻulu manaʻo:

Ma ke ʻano he mea semiconductor hou, ua hōʻike ka waʻa kristal silicon carbide i nā pono he nui a me nā kahua noi ākea i ka ʻoihana semiconductor. ʻO kona mau waiwai wela kiʻekiʻe, ka neʻe ʻana o ka electron kiʻekiʻe, ke kū'ē ʻana i ka radiation kiʻekiʻe a me nā ʻano hoʻololi wikiwiki e kūpono ia no nā noi mana kiʻekiʻe, alapine kiʻekiʻe a me nā noi wela kiʻekiʻe. Mai nā mea uila mana kiʻekiʻe a hiki i nā amplifiers mana RF, mai nā mea optoelectronic a hiki i nā mea uila wela kiʻekiʻe, uhi ka laulā noi o nā ipu kristal silicon carbide i nā kahua he nui, a ua hoʻokomo i ka ikaika hou i ka hoʻomohala ʻana o ka ʻenehana semiconductor. Me ka holomua mau o ka ʻenehana a me ka noiʻi hohonu, e hoʻonui hou ʻia ka manaʻolana noi o nā waʻa kristal silicon carbide i ka ʻoihana semiconductor, e hana ana i nā lako uila ʻoi aku ka maikaʻi, hilinaʻi a holomua hoʻi no mākou.
