Izingxenye ze-semiconductor - isisekelo se-graphite esimbozwe yi-SiC
Izisekelo ze-graphite ezimbozwe yi-SiC zivame ukusetshenziselwa ukusekela nokushisa ama-substrate e-single crystal kumishini ye-metal-organic chemical vapor deposition (MOCVD). Ukuzinza kokushisa, ukufana kokushisa kanye nezinye izilinganiso zokusebenza kwesisekelo se-graphite esimbozwe yi-SiC kudlala indima ebalulekile ekhwalithini ye-epi...Funda kabanzi -
Kungani i-Silicon njenge-chip ye-semiconductor?
I-semiconductor yinto ekwaziyo ukudlulisa ugesi ekushiseni kwegumbi phakathi komqhubi kanye ne-insulator. Njengentambo yethusi empilweni yansuku zonke, intambo ye-aluminium iyi-conductor, kanti irabha iyi-insulator. Ngokombono wokudlulisa ugesi: i-semiconductor ibhekisela ku-conductivity...Funda kabanzi -
Umphumela wokusila ezimpahleni ze-zirconia ceramics
Umphumela wokushiswa kwe-sintering ezimpahleni ze-zirconia ceramics Njengohlobo lwezinto ze-ceramic, i-zirconium inamandla aphezulu, ubulukhuni obuphezulu, ukumelana okuhle nokuguguleka, ukumelana ne-asidi ne-alkali, ukumelana nokushisa okuphezulu kanye nezinye izakhiwo ezinhle kakhulu. Ngaphezu kokusetshenziswa kabanzi emkhakheni wezimboni,...Funda kabanzi -

Izinto eziyinhloko zokukhula kwe-sic ezithuthukisiwe
Lapho ikristalu ye-silicon carbide ikhula, "indawo" yokuxhumana kokukhula phakathi kwesikhungo se-axial sekristalu kanye nomphetho ihlukile, ukuze ukucindezeleka kwekristalu onqenqemeni kukhuphuke, futhi umphetho wekristalu kulula ukukhiqiza "amaphutha aphelele" ngenxa yolwazi...Funda kabanzi -
Ikhiqizwa kanjani i-silicon carbide e-reaction-sintered?
I-silicon carbide eshintsha ukusabela iyindlela ebalulekile yokukhiqiza izinto ze-ceramic ezisebenza kahle kakhulu. Le ndlela isebenzisa ukwelashwa kokushisa kwemithombo ye-carbon ne-silicon emazingeni okushisa aphezulu ukuze ibenze basabele ekwakheni i-silicon carbide ceramics. 1. Ukulungiswa kwezinto zokusetshenziswa. Izinto zokusetshenziswa ze-r...Funda kabanzi -
Isikebhe sekristalu se-silicon carbide, izinto ezintsha ze-silicon carbide ziletha amandla aqinile
Isikebhe sekristalu se-silicon carbide siwubuchwepheshe obusha kakhulu, obushintshe indlela yendabuko yokukhiqiza. Siyakwazi ukuhlanganisa i-silicon carbide nezinye ukwakha isakhiwo esiqinile kakhulu, esingathuthukisa ngempumelelo ukusebenza kahle kwenqubo yokukhiqiza, futhi singathuthukisa kakhulu ...Funda kabanzi -
Ukusetshenziswa kanye nemakethe ye-tantalum carbide coating
Ubulukhuni be-carbide ye-tantalum, indawo yokuncibilika ephezulu, ukusebenza kahle kwezinga lokushisa eliphezulu, okusetshenziswa kakhulu njengesithasiselo se-carbide esiqinisiwe. Ubulukhuni bokushisa, ukumelana nokushaqeka kokushisa kanye nokumelana nokushiswa kokushisa kwe-carbide esiqinisiwe kungathuthukiswa kakhulu ngokwandisa usayizi wezinhlamvu ze-carbi ye-tantalum...Funda kabanzi -
