I-SiC Embozwe

I-VET ENERGY, umenzi ohamba phambili we-CVD SIC coating eShayina

Izinto Ezishintsha Ikusasa

I-Silicon carbide (i-SiC) iyinto entsha ye-semiconductor ehlanganisiwe. I-Silicon carbide ine-band gap enkulu (cishe i-silicon ephindwe kathathu), amandla ensimu abucayi kakhulu (cishe i-silicon ephindwe kayishumi), ukuhanjiswa kokushisa okuphezulu (cishe i-silicon ephindwe kathathu). Iyinto ebalulekile ye-semiconductor yesizukulwane esilandelayo. Izembozo ze-SiC zisetshenziswa kabanzi embonini ye-semiconductor kanye ne-solar photovoltaics. Ikakhulukazi, ama-susceptors asetshenziswa ekukhuleni kwe-epitaxial kwama-LED kanye ne-Si single crystal epitaxy adinga ukusetshenziswa kwe-SiC coating. Ngenxa yokwenyuka okunamandla kwama-LED embonini yokukhanyisa nokubonisa, kanye nentuthuko enamandla yemboni ye-semiconductor,Umkhiqizo wokumboza we-SiCAmathemba amahle kakhulu.

INSIMU YESICELO

Ukusetshenziswa komkhiqizo kanye nokusebenza kwawo Izinhlelo zokusebenza zomkhiqizo kanye nokusetshenziswa kwawo

Uma usebenzisa imboni yekristalu eyodwa, iGaN, i-AlN, i-sapphire nezinye izisekelo ze-MOCVD. -Isembozo sesisekelo se-Graphite sokukhula kwe-silicon epitaxial yekristalu eyodwa

Ubumsulwa, Isakhiwo se-SEM, ukuhlaziywa kobukhulu beUkugqoka kwe-SiC

Ubumsulwa be-SiC coatings ku-graphite ngokusebenzisa i-CVD bufinyelela ku-99.9995%. Isakhiwo sayo siyi-fcc. Amafilimu e-SiC ambozwe ku-graphite aqondiswe ku-(111) njengoba kuboniswe kudatha ye-XRD (Isithombe 1) okubonisa ikhwalithi yayo ephezulu yekristalu. Ubukhulu befilimu ye-SiC bufana kakhulu njengoba kuboniswe ku-Fig. 2.

Idatha ye-SEM yefilimu encane ye-CVD SiC, usayizi wekristalu ungama-2 ~ 1 Opm

Isithombe 2: iyunifomu yobukhulu bamafilimu e-SiC

Isakhiwo sekristalu sefilimu ye-CVD SiC siyisakhiwo se-cubic esigxile ebusweni, futhi ukuqondiswa kokukhula kwefilimu kusondele ku-100%
