Boti la kristalo la silicon carbide: chida chatsopano cha mafakitale a semiconductor

Chifukwa cha kupita patsogolo kwa sayansi ndi ukadaulo kosalekeza, makampani opanga zinthu zamagetsi zamagetsi (semiconductor) akufunikira kwambiri zipangizo zogwirira ntchito bwino komanso zogwira ntchito bwino. Pankhani imeneyi,bwato la kristalo la silicon carbidelakhala lofunika kwambiri chifukwa cha makhalidwe ake apadera komanso malo ambiri ogwiritsira ntchito. Pepalali lifotokoza ubwino ndi kugwiritsa ntchito maboti a silicon carbide crystal mumakampani opanga ma semiconductor, ndikuwonetsa udindo wake wofunikira pakulimbikitsa chitukuko cha ukadaulo wa ma semiconductor.

Ubwino:

1.1 Makhalidwe a kutentha kwambiri:

Boti la kristalo la silicon carbideIli ndi kukhazikika kwa kutentha kwambiri komanso mphamvu yoyendetsera kutentha, imatha kugwira ntchito pamalo otentha kwambiri, komanso imatha kupirira kutentha kopitilira kutentha kwa chipinda. Izi zimapatsa maboti a SIC mwayi wapadera pakugwiritsa ntchito mphamvu zambiri komanso kutentha kwambiri, monga zamagetsi zamagetsi, magalimoto amagetsi ndi ndege.

1.2 Kuyenda kwa ma elekitironi kwambiri:

Kuyenda kwa ma elekitironi kwa maboti a kristalo a silicon carbide ndi kwakukulu kwambiri kuposa kwa zipangizo zachikhalidwe za silicon, zomwe zikutanthauza kuti zimatha kukhala ndi mphamvu zambiri komanso kugwiritsa ntchito mphamvu zochepa. Izi zimapangitsa kuti boti la kristalo la silicon carbide likhale ndi mwayi waukulu wogwiritsidwa ntchito m'munda wa zida zamagetsi zamagetsi zamagetsi, komanso kulumikizana kwa ma wailesi pafupipafupi.

1.3 Kukana kwambiri kwa kuwala kwa dzuwa:

Boti la silicon carbide crystal lili ndi mphamvu yolimbana ndi kuwala kwa dzuwa ndipo limatha kugwira ntchito mokhazikika pamalo omwe ali ndi kuwala kwa dzuwa kwa nthawi yayitali. Izi zimapangitsa kuti maboti a SIC akhale othandiza kwambiri m'magawo a nyukiliya, ndege ndi chitetezo, komwe amapereka njira zodalirika komanso zokhalitsa.

1.4 Makhalidwe osinthira mwachangu:

Chifukwa bwato la silicon carbide crystal lili ndi kuyenda kwa ma elekitironi ambiri komanso kukana kochepa, limatha kusinthasintha mwachangu komanso kutayika kochepa kwa kusintha. Izi zimapangitsa bwato la silicon carbide kukhala lothandiza kwambiri pakupanga ma electronic converters amphamvu, ma power transmission ndi ma drive system, zomwe zingathandize kukonza mphamvu ndikuchepetsa kutayika kwa mphamvu.

Mapulogalamu:

2.1 Zipangizo zamagetsi zamphamvu kwambiri:

maboti a kristalo a silicon carbideali ndi mwayi wosiyanasiyana wogwiritsa ntchito pamagetsi amphamvu kwambiri, monga ma inverter a magalimoto amagetsi, makina opangira mphamvu ya dzuwa, oyendetsa magalimoto amafakitale, ndi zina zotero. Kukhazikika kwawo kutentha kwambiri komanso kuyenda kwa ma elekitironi ambiri kumathandiza kuti zipangizozi zigwire bwino ntchito komanso zikhale zochepa.

2.2 RF mphamvu amplifier:

Kuyenda kwa ma elekitironi ambiri komanso kuchepa kwa kutayika kwa maboti a kristalo a silicon carbide kumapangitsa kuti akhale zida zabwino kwambiri zogwiritsira ntchito ma amplifiers amphamvu a RF. Ma amplifiers amphamvu mu machitidwe olumikizirana a RF, ma radar ndi zida za wailesi amatha kusintha kuchuluka kwa mphamvu ndi magwiridwe antchito a makina pogwiritsa ntchito maboti a kristalo a silicon carbide.

2.3 Zipangizo zamagetsi:

Maboti a kristalo a silicon carbide amagwiritsidwanso ntchito kwambiri pazida zamagetsi. Chifukwa cha kukana kwake kutentha kwambiri komanso kukhazikika kwa kutentha, maboti a kristalo a silicon carbide angagwiritsidwe ntchito mu ma laser diode, ma photodetector ndi ma fiber optic communications, zomwe zimapereka mayankho odalirika komanso ogwira mtima.

 

2.4 Zipangizo zamagetsi zotentha kwambiri:

Kukhazikika kwa kutentha kwa boti la silicon carbide crystal kumapangitsa kuti ligwiritsidwe ntchito kwambiri pazida zamagetsi m'malo otentha kwambiri. Mwachitsanzo, kuyang'anira ma reactor a nyukiliya m'gawo la mphamvu za nyukiliya, masensa otentha kwambiri ndi makina owongolera injini m'gawo la ndege.

 

Powombetsa mkota:

Monga chida chatsopano cha semiconductor, bwato la silicon carbide crystal lawonetsa zabwino zambiri komanso malo ambiri ogwiritsira ntchito mumakampani opanga ma semiconductor. Makhalidwe ake otentha kwambiri, kuyenda kwa ma elekitironi ambiri, kukana kwa radiation yambiri komanso mawonekedwe ake osinthira mwachangu zimapangitsa kuti likhale labwino kwambiri pakugwiritsa ntchito mphamvu zambiri, ma frequency ambiri komanso kutentha kwambiri. Kuyambira pazida zamagetsi zamagetsi zamagetsi mpaka ma amplifiers amphamvu a RF, kuyambira pazida zamagetsi zamagetsi mpaka pazida zamagetsi zamagetsi kutentha kwambiri, mitundu yosiyanasiyana ya zombo za silicon carbide crystal imaphimba madera ambiri, ndipo yawonjezera mphamvu zatsopano pakukula kwa ukadaulo wa semiconductor. Ndi kupita patsogolo kosalekeza kwa ukadaulo ndi kafukufuku wozama, chiyembekezo cha kugwiritsa ntchito maboti a silicon carbide crystal mumakampani opanga ma semiconductor chidzakulitsidwa kwambiri, ndikupanga zida zamagetsi zogwira mtima, zodalirika komanso zapamwamba kwa ife.
