Sic - silicon carbide

Silicon Carbide adapezeka mu 1893 ngati mafakitale ogulitsa magudumu ndi mabuleki aulemu. Pafupifupi pakati pa zaka za m'ma 1900, anzeru kwambiri amagwiritsa ntchito pophatikiza ukadaulo wa LED. Kuyambira pamenepo, wachulukitsa ntchito zogwirira ntchito za semiconductor chifukwa cha mwayi wake. Izi zikuwoneka m'njira zosiyanasiyana komanso kunja kwa malo ogulitsa semiconducy. Ndi lamulo la Moore akuwoneka kuti ndi malire, makampani ambiri mkati mwa akatswiri ogulitsa semicon akuyang'ana ku Sicon carbide monga Semonictor Christ. SIC imatha kupangidwa pogwiritsa ntchito ma pollypes angapo a sic, ngakhale mkati mwa akatswiri a semiconducy, magawo ambiri ali 4h-sic, ndi 6h- kukhala osagwirizana kwambiri chifukwa msika wa sic wakula. Mukamanena za 4h- ndi 6h- dildicon Carbide, H imayimira kapangidwe ka kagawo ka kristalo. Chiwerengerochi chikuyimira maatomu okhazikika mkati mwa mawonekedwe a galasi, izi zikufotokozedwa patsamba la SVM pansipa. Ubwino wa Sicon Carlide Mphamvu Pali maubwino ambiri ogwiritsa ntchito silikicone carbide bormial a silicon. Chimodzi mwa zabwino za nkhaniyi ndi kuuma kwake. Izi zimapereka zowonjezera zabwino zambiri, kuthamanga kwambiri, kutentha kwambiri ndi / kapena magetsi apamwamba kwambiri. Silicon carbide ofera amakhala ndi mawonekedwe ambiri, omwe amatanthauza kusamutsa kutentha kuchokera kwina kupita ku chitsime china. Izi zimathandizira mawonekedwe ake zamagetsi ndipo pamapeto pake miniaturization, chimodzi mwa zolinga zomwe zimasinthana ndi zofunda za SISI. Mafuta owonda anzeru amapezanso ndi mwayi wokhala ndi mafuta. Kuchulukitsa kwa mafuta ndi kuchuluka kwake ndikuwongolera zomwe zimakulitsa kapena kupanga mgwirizano momwe zimakhalira kapena kuzizira. Kulongosola kofala kwambiri ndi ayezi, ngakhale kumakhala kosiyana ndi zitsulo zambiri, kukulitsa ngati kuzizira ndikumatha. Silicon carbide yotsika mtengo yowonjezera mafuta imatanthawuza kuti sizisintha kwambiri kapena mawonekedwe ngati zimatenthedwa kapena kuthiridwa pansi, zomwe zimapangitsa kuti ikhale yabwino mu zidutswa zazing'ono ndikunyamula ma transtors ambiri ku chip. Pali mwayi wina waukulu wa magawo awa ndi kukana kwawo kwamphamvu kwa mafuta. Izi zikutanthauza kuti ali ndi kuthekera kusintha kutentha mwachangu osaswa kapena kusweka. Izi zimapangitsa kuti mwayi wowoneka bwino akamapanga zida monga momwe zimakhalira ndi mawonekedwe ena olimbitsa thupi omwe amasintha moyo ndi magwiridwe antchito a silicon poyerekeza ndi silicon yambiri. Pamwamba pa kuthekera kwake, ndi gawo lalikulu kwambiri ndipo silimachita ndi acid, alkalis kapena mchere wosungunula pamatenthedwe mpaka 800 Cels C. Izi zimapereka mphamvu izi pakugwiritsa ntchito kwawo ndikuthandizanso kuthandizira kuti azitha kuchita zambiri pamapulogalamu ambiri. Mphamvu yake pamatenthedwe kwambiri imathandiziranso kugwira ntchito mosamala pamatenthedwe oposa 1600 ° C. Izi zimapangitsa kukhala gawo lapansi loyenereranso kugwiritsa ntchito kutentha kulikonse.
