Zinthu za semiconductor za silicon carbide

Silikoni kabide (SiC)Zipangizo za semiconductor ndi zomwe zakula kwambiri pakati pa ma semiconductors a wide band gap omwe apangidwa. Zipangizo za semiconductor za SiC zili ndi mphamvu yayikulu yogwiritsira ntchito pa kutentha kwambiri, ma frequency ambiri, mphamvu zambiri, ma photoelectronics ndi zida zotsutsana ndi ma radiation chifukwa cha ma electron gap awo ambiri, magetsi ambiri owonongeka, kutentha kwambiri, kuyenda kwa ma elekitironi ambiri komanso kukula kochepa. Silicon carbide ili ndi ntchito zosiyanasiyana: chifukwa cha ma electron gap ake ambiri, ingagwiritsidwe ntchito kupanga ma diode abuluu otulutsa kuwala kapena ma ultraviolet detectors omwe sakhudzidwa kwambiri ndi kuwala kwa dzuwa; Chifukwa mphamvu yamagetsi kapena magetsi imatha kupirira kasanu ndi katatu kuposa silicon kapena gallium arsenide, makamaka yoyenera kupanga zida zamphamvu kwambiri monga ma diode amagetsi ambiri, ma triode amphamvu, ma microwave olamulidwa ndi silicon komanso amphamvu kwambiri; Chifukwa cha liwiro lalikulu la ma elekitironi osuntha, imatha kupangidwa kukhala zida zosiyanasiyana zama frequency apamwamba (RF ndi microwave);Silikoni kabidendi woyendetsa bwino kutentha ndipo amayendetsa kutentha bwino kuposa zipangizo zina zilizonse za semiconductor, zomwe zimapangitsa kuti zipangizo za silicon carbide zizigwira ntchito kutentha kwambiri.

Mwachitsanzo, APEI ikukonzekera kupanga makina ake oyendetsa magalimoto a DC omwe ali ndi chilengedwe chapamwamba kwambiri a Venus Explorer (VISE) ya NASA pogwiritsa ntchito zida za silicon carbide. Cholinga chake ndi kuyika maloboti ofufuza pamwamba pa Venus.

Kuphatikiza apo, skabide wa siliconIli ndi mgwirizano wamphamvu wa ionic covalent, ili ndi kuuma kwakukulu, kutentha kumadutsa mkuwa, kutentha kumatuluka bwino, kukana dzimbiri kuli kolimba kwambiri, kukana kuwala kwa dzuwa, kukana kutentha kwambiri komanso kukhazikika kwa mankhwala ndi zina, ili ndi ntchito zambiri m'munda waukadaulo wa ndege. Mwachitsanzo, kugwiritsa ntchito zinthu za silicon carbide kukonzekera zombo zapamlengalenga kuti akatswiri a zakuthambo, ofufuza azikhala ndi kugwira ntchito.
