No ka noi ʻana i nā waʻa wafer silicon carbide ma ke kahua semiconductor

Ma ke kahua semiconductor, he mea koʻikoʻi ke koho ʻana i nā mea i ka hana a me ka hoʻomohala kaʻina hana. I nā makahiki i hala iho nei,nā wafer silika carbide, ma ke ʻano he mea e puka mai nei, ua hoʻokipa nui ʻia a ua hōʻike i ka mana nui no ka noi ʻana ma ke kahua semiconductor.

Waʻa wafer silikonihe mea lau lahilahi i ulu mai ka silika carbide (SiC) hookahi aniani. Hoʻohālikelike ʻia me nā mea semiconductor maʻamau,nā waʻa wafer silicon carbideloaʻa nā pono kūʻokoʻa he nui. ʻO ka mea mua, loaʻa iā ia kahi ākea ākea o ka ikehu, hāʻawi iā ia i ka hana maikaʻi loa i nā noi kiʻekiʻe-mehana a me nā mana kiʻekiʻe.Nā waʻa wafer silikonikahiki ke pale aku i ka neʻe ʻana o ka electron a me ka neʻe ʻana o ka mea lawe i nā kaiapuni kiʻekiʻe, no laila e hōʻike ana i ka nalowale o ka ikehu haʻahaʻa a me ka ʻoi aku ka maikaʻi o nā noi kiʻekiʻe, kiʻekiʻe-mehana a me nā noi kiʻekiʻe.

ʻO ka lua,nā waʻa wafer silicon carbideloaʻa i ka conductivity wela maikaʻi a me ke kūpaʻa wela. ʻO ia ke kumu kumu kūpono no nā mea hana semiconductor mana kiʻekiʻe, hiki ke alakaʻi maikaʻi a hoʻopau i ka wela, hoʻomaikaʻi i ka hilinaʻi a me ka paʻa o ka hāmeʻa.Nā waʻa wafer silikonikaloaʻa nō hoʻi nā waiwai mechanical maikaʻi a me ke kūpaʻa kemika, hiki ke pale aku i ke koʻikoʻi a me ka corrosion kaiapuni, a hoʻonui i ke ola lawelawe o ka hāmeʻa.

Kahi mea hou aʻe,nā waʻa wafer silicon carbideloaʻa nō hoʻi nā waiwai uila maikaʻi loa. Loaʻa iā ia ka mobility electron kiʻekiʻe a me ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa, hiki i ka wikiwiki o ka hoʻololi ʻana a me ka haʻahaʻa haʻahaʻa. Hana kēia i nā wafers silicon carbide i koho maikaʻi loa no nā mea mana kiʻekiʻe a me nā mea uila uila kiʻekiʻe, e hāpai ana i ka hoʻomohala ʻana i ka ʻenehana semiconductor.

Me ka hoʻomau mau ʻana o ka ʻenehana semiconductor a me ka piʻi ʻana o ka noi no ka mana kiʻekiʻe, kiʻekiʻe-mehana, kiʻekiʻe-frequency a me ka wikiwiki wikiwiki, nā manaʻo noinā wafer silika carbideua lilo i ākea. Hiki ke hoʻohanaʻia ma nāʻano likeʻole, e like me ka uila uila, nā leka uila, nā kaʻa uila, aerospace, a me nā mea'ē aʻe. ʻōnaehana hilinaʻi. Ma ke kahua o ke kelepona uila, hiki ke hoʻohana ʻia nā wafers silicon carbide i nā ʻāpana koʻikoʻi e like me nā mana amplifiers kiʻekiʻe a me nā hoʻololi lekiō no ka hoʻokō ʻana i ka hoʻoili ʻikepili paʻa.

I ka hōʻuluʻulu ʻana, ua hōʻike nā moku wafer silicon carbide, ma ke ʻano he mea e puka mai nei, i nā manaʻo noiʻi ākea ma ke kahua semiconductor. ʻO kāna mau mea uila maikaʻi loa, wela a me nā mea hana mechanical e lilo ia i mea kūpono no ka mana kiʻekiʻe, ka wela kiʻekiʻe, ke alapine kiʻekiʻe a me nā noi wikiwiki kiʻekiʻe. Ke hoʻomau nei ka piʻi ʻana o nā koi no ka ikaika o ka ikehu a me ka hana, manaʻo ʻia nā wafers silicon carbide e pāʻani i kahi hana koʻikoʻi i ka ʻoihana semiconductor a hoʻolaha i ka hoʻomohala ʻana o ka ʻenehana semiconductor.
