Lokhu kunikeza izikebhe ze-SIC inzuzo eyingqayizivele emandleni aphezulu kanye nezicelo zokushisa okuphezulu, njengama-electronics amandla, izimoto zikagesi kanye ne-aerospace.

1.2 Ukuhamba kwama-electron aphezulu:

Ukuhamba kwe-electron yezikebhe ze-silicon carbide crystal kuphakeme kakhulu kunokwezinto ze-silicon zendabuko, okusho ukuthi kungafinyelela ukuminyana okuphezulu kwamanje kanye nokusetshenziswa kwamandla okuphansi. Lokhu kwenza isikebhe se-silicon carbide crystal sibe nethemba elibanzi lohlelo lokusebenza emkhakheni wefrikhwensi ephezulu, imishini yamandla aphezulu kagesi kanye nokuxhumana kwamafrikhwensi omsakazo.

1.3 Ukumelana nemisebe ephezulu:

isikebhe se-silicon carbide crystal sinokumelana okuqinile emisebeni futhi singasebenza ngokuzinza endaweni yemisebe isikhathi eside. Lokhu kwenza izikebhe ze-SIC zibe wusizo emkhakheni we-nuclear, i-aerospace kanye nezokuvikela, lapho zinikeza khona izixazululo ezinokwethenjelwa kakhulu nezihlala isikhathi eside.

1.4 Izici zokushintsha ngokushesha:

Ngenxa yokuthi isikebhe se-silicon carbide crystal sinokuhamba okuphezulu kwe-electron nokumelana okuphansi, singakwazi ukufeza isivinini sokushintsha okusheshayo nokulahlekelwa kokushintsha okuphansi. Lokhu kwenza isikebhe se-silicon carbide sibe yinzuzo enkulu ekuguquleni amandla kagesi, ukudluliswa kwamandla kanye nezinhlelo zokushayela, ezingathuthukisa ukusebenza kahle kwamandla nokunciphisa ukulahleka kwamandla.

Izicelo:

2.1 Imishini kagesi enamandla amakhulu:

izikebhe ze-silicon carbide crystalbabe nohlu olubanzi lwamathemba okufaka isicelo kuzinhlelo zokusebenza zamandla aphezulu, njengama-inverter ezimoto zikagesi, izinhlelo zokuphehla amandla elanga, abashayeli bezimoto zezimboni, njll. Ukuzinza kwabo kwezinga lokushisa eliphezulu nokuhamba kwama-electron aphezulu kuvumela lawa madivaysi ukuba afinyelele ukusebenza kahle okukhulu kanye namavolumu amancane. .

2.2 RF isikhulisi samandla:

Ukuhamba kwama-electron aphezulu kanye nezici zokulahlekelwa okuphansi kwezikebhe ze-silicon carbide crystal zizenza izinto ezilungele izikhulisamandla ze-RF. Izikhulisamandla ezinhlelweni zokuxhumana ze-RF, ama-radar nezinto zomsakazo zingathuthukisa ukuminyana kwamandla kanye nokusebenza kwesistimu ngokusebenzisa izikebhe ze-silicon carbide crystal.

2.3 Amadivayisi we-Optoelectronic:

Izikebhe ze-silicon carbide crystal nazo zisetshenziswa kabanzi emkhakheni wemishini ye-optoelectronic. Ngenxa yokumelana kwayo nemisebe ephezulu nokuzinza okuphezulu kwezinga lokushisa, izikebhe ze-silicon carbide crystal zingasetshenziswa kuma-laser diode, ama-photodetectors kanye nezokuxhumana ze-fiber optic, ezihlinzeka ngezixazululo ezinokwethenjelwa kakhulu nezisebenza kahle.

 

2.4 Izisetshenziswa ze-elekthronikhi ezinokushisa okuphezulu:

Ukuzinza kwezinga lokushisa eliphezulu kwesikebhe se-silicon carbide crystal kuyenza isetshenziswe kabanzi kumadivayisi kagesi endaweni yokushisa ephezulu. Isibonelo, ukuqapha kwe-nuclear reactor emkhakheni wamandla enuzi, izinzwa zokushisa okuphezulu kanye nezinhlelo zokulawula injini emkhakheni we-aerospace.

 

Ngokufigqiwe:

Njengempahla entsha ye-semiconductor, isikebhe se-silicon carbide crystal sibonise izinzuzo eziningi kanye nezinkambu ezibanzi zokusetshenziswa embonini ye-semiconductor. Izici zayo zokushisa eziphakeme, ukuhamba kwe-electron ephezulu, ukumelana nemisebe ephezulu kanye nezici zokushintsha ngokushesha kuyenza ilungele amandla aphezulu, imvamisa ephezulu kanye nezicelo zokushisa okuphezulu. Kusukela kumishini kagesi enamandla amakhulu kuye kwezikhulisamandla ze-RF, kusukela kumishini ye-optoelectronic kuya kumishini kagesi enezinga lokushisa eliphezulu, uhla lokusetshenziswa kwemikhumbi ye-silicon carbide crystal luhlanganisa izinkambu eziningi, futhi lufake ubungqabavu obusha ekuthuthukisweni kobuchwepheshe be-semiconductor. Ngokuqhubeka okuqhubekayo kobuchwepheshe kanye nocwaningo olujulile, ithemba lokufaka isicelo sezikebhe ze-silicon carbide crystal embonini ye-semiconductor lizophinde linwetshwe, lisenze imishini ye-elekthronikhi esebenza kahle kakhulu, ethembekile futhi ethuthukisiwe.
