Yiziphi izithiyo zobuchwepheshe ze-silicon carbide?Ⅱ
Izinkinga zobuchwepheshe ekukhiqizeni ngokuzinzile kwama-wafers e-silicon carbide ekhwalithi ephezulu nokusebenza okuzinzile kufaka phakathi: 1) Njengoba amakristalu edinga ukukhula endaweni evalwe ngezinga lokushisa eliphezulu ngaphezu kuka-2000 ° C, izidingo zokulawula izinga lokushisa ziphakeme kakhulu; 2) Njengoba i-silicon carbide inokuningi ...Funda kabanzi -
Yiziphi izithiyo zobuchwepheshe ku-silicon carbide?
Isizukulwane sokuqala sezinto zokwakha ze-semiconductor simelelwa yi-silicon yendabuko (Si) ne-germanium (Ge), okuyisisekelo sokukhiqiza isifunda esihlanganisiwe. Asetshenziswa kakhulu kuma-low-voltage, low-frequency, kanye nama-low-power transistors nama-detectors. Ngaphezu kuka-90% womkhiqizo we-semiconductor...Funda kabanzi -
Yenziwa kanjani i-SiC micro powder?
I-SiC single crystal iyisisetshenziswa se-semiconductor yeQembu IV-IV esakhiwe izakhi ezimbili, u-Si no-C, ngesilinganiso se-stoichiometric esingu-1:1. Ukuqina kwayo kungokwesibili ngemva kwedayimane. Ukuncishiswa kwekhabhoni yendlela ye-silicon oxide yokulungiselela i-SiC kusekelwe ikakhulukazi kufomula yokusabela kwamakhemikhali elandelayo...Funda kabanzi -
Izendlalelo ze-epitaxial ziwasiza kanjani amadivayisi we-semiconductor?
Umsuka wegama le-epitaxial wafer Okokuqala, ake sandise umqondo omncane: ukulungiswa kwe-wafer kuhlanganisa izixhumanisi ezimbili ezinkulu: ukulungiswa kwe-substrate kanye nenqubo ye-epitaxial. I-substrate iyicwecwe elenziwe nge-semiconductor single crystal material. I-substrate ingangena ngqo embonini ye-wafer ...Funda kabanzi -
Isingeniso ku-chemical vapor deposition (CVD) ubuchwepheshe bokufakwa kwefilimu emincane
I-Chemical Vapor Deposition (CVD) iwubuchwepheshe obubalulekile bokufakwa kwefilimu emincane, evame ukusetshenziselwa ukulungisa amafilimu ahlukahlukene asebenzayo nezinto zongqimba oluncane, futhi isetshenziswa kabanzi ekukhiqizeni ama-semiconductor nakweminye imikhakha. 1. Umgomo wokusebenza we-CVD Enqubweni ye-CVD, isandulela segesi (eyodwa noma i-mo...Funda kabanzi -
Imfihlo "yegolide elimnyama" ngemuva kwemboni ye-photovoltaic semiconductor: isifiso nokuncika ku-isostatic graphite
I-graphite ye-Isostatic iyinto ebaluleke kakhulu kuma-photovoltaics nama-semiconductors. Ngokukhula okusheshayo kwezinkampani zasekhaya ze-isostatic graphite, ukubusa kwezinkampani zakwamanye amazwe eChina kwephukile. Ngocwaningo oluqhubekayo oluzimele kanye nentuthuko kanye nempumelelo kwezobuchwepheshe, ...Funda kabanzi -
Ukwembula Izimpawu Ezibalulekile Zezikebhe Ze-Graphite Ekukhiqizeni I-Semiconductor Ceramics
Izikebhe ze-Graphite, ezaziwa nangokuthi izikebhe ze-graphite, zidlala indima ebalulekile ezinqubweni eziyinkimbinkimbi zokwenziwa kwe-semiconductor ceramics. Le mikhumbi ekhethekile isebenza njengabathwali abathembekile be-wafers ye-semiconductor ngesikhathi sokwelashwa okushisa kakhulu, iqinisekisa ukucubungula okunembile nokulawulwayo. Nge...Funda kabanzi -
Isakhiwo sangaphakathi semishini yeshubhu yesithando somlilo sichazwa ngokuningiliziwe
Njengoba kuboniswe ngenhla, kuyinto evamile Ingxenye yokuqala: I-Heating Element (ikhoyili yokushisa) : etholakala eduze kweshubhu yesithando somlilo, ngokuvamile eyenziwe ngezintambo zokumelana, ezisetshenziselwa ukushisa ngaphakathi kweshubhu lomlilo. I-Quartz Tube: Umnyombo wesithando somlilo se-oxidation esishisayo, esenziwe nge-quartz ehlanzekile kakhulu ekwazi ukumelana ne-hig...Funda kabanzi -
Imithelela ye-SiC substrate nezinto ze-epitaxial ezicini zedivayisi ye-MOSFET
Ukukhubazeka kukanxantathu Ukukhubazeka kukanxantathu yiziphambeko ze-morphological ezibulala kakhulu ezendlalelo ze-SiC epitaxial. Inombolo enkulu yemibiko yezincwadi ibonise ukuthi ukwakheka kwamaphutha angama-triangular kuhlobene nefomu le-crystal ye-3C. Kodwa-ke, ngenxa yezindlela ezihlukene zokukhula, i-morphology yabaningi ...Funda kabanzi
