Silicon carbide thepa Le likarolo tsa eona

Sesebelisoa sa semiconductor ke setsi sa lisebelisoa tsa mochini oa sejoale-joale, se sebelisoang haholo likhomphutha, lisebelisoa tsa elektroniki tsa bareki, likhokahano tsa marang-rang, lisebelisoa tsa elektroniki tsa likoloi le libaka tse ling tsa mantlha, indasteri ea semiconductor e entsoe haholo ka likarolo tse 'ne tsa mantlha: lipotoloho tse kopaneng, lisebelisoa tsa optoelectronic, sesebelisoa sa discrete, sensor, e ikarabellang ho feta 80% ea lipotoloho tse kopantsoeng, hangata le semiconductor le seketsoana se kopaneng sa potoloho.

Potoloho e kopantsoeng, ho latela sehlopha sa sehlahisoa e arotsoe haholo ka mekhahlelo e mene: microprocessor, memori, lisebelisoa tsa logic, likarolo tsa simulator. Leha ho le joalo, ka ho atolosoa ho tsoelang pele ha tšimo ea ts'ebeliso ea lisebelisoa tsa semiconductor, liketsahalo tse ngata tse khethehileng li hloka hore li-semiconductors li khone ho khomarela tšebeliso ea mocheso o phahameng, mahlaseli a matla, matla a phahameng le libaka tse ling, li se ke tsa senya moloko oa pele le oa bobeli. lisebelisoa tsa semiconductor ha li na matla, kahoo moloko oa boraro oa lisebelisoa tsa semiconductor o bile teng.

Hajoale, lisebelisoa tsa semiconductor tsa semiconductor tse pharaletseng tsa sehlopha se emeloa kesilicon carbide(SiC), gallium nitride (GaN), zinc oxide (ZnO), daemane, aluminium nitride (AlN) li lula 'marakeng o hlahelletseng ka melemo e meholo, ka kakaretso e bitsoang lisebelisoa tsa semiconductor tsa moloko oa boraro. Moloko oa boraro oa thepa ea semiconductor e nang le lekhalo le pharaletseng la lekhalo, e phahamisa tšimo ea motlakase ea ho senyeha, mocheso oa motlakase, tekanyo ea elektronike e tletseng matla le bokhoni bo phahameng ba ho hanyetsa mahlaseli, ho loketse ho etsa mocheso o phahameng, maqhubu a phahameng, ho hanyetsa mahlaseli le lisebelisoa tse phahameng tsa matla. , eo hangata e tsejoang e le lisebelisoa tse pharaletseng tsa semiconductor (bophara bo hanetsoeng bo boholo ho feta 2.2 eV), eo hape e bitsoang mocheso o phahameng lisebelisoa tsa semiconductor. Ho tsoa lipatlisisong tsa hajoale mabapi le lisebelisoa le lisebelisoa tsa semiconductor tsa moloko oa boraro, lisebelisoa tsa silicon carbide le gallium nitride semiconductor li holile haholoanyane, 'me.theknoloji ea silicon carbideke eona e hōlileng ka ho fetisisa, ha lipatlisiso tsa zinki oxide, taemane, aluminium nitride le lisebelisoa tse ling li ntse li le boemong ba pele.

Thepa le Thepa ea bona:

Silicon carbidethepa e sebelisoa haholo ka ceramic dibering bolo, li-valve, thepa ea semiconductor, gyros, lisebelisoa tsa ho lekanya, sefofane le masimo a mang, e fetohile thepa e ke keng ea nkeloa sebaka masimong a mangata a indasteri.

SiC ke mofuta oa superlattice ea tlhaho le mofuta o tloaelehileng oa homogeneous polytype. Ho na le malapa a fetang 200 (a tsejoang hona joale) homotypic polytypic ka lebaka la phapang ea tatellano ea ho paka pakeng tsa Si le C diatomic layers, e lebisang meahong e fapaneng ea kristale. Ka hona, SiC e loketse haholo bakeng sa moloko o mocha oa lisebelisoa tsa substrate diode (LED), lisebelisoa tse phahameng tsa elektronike.
