Mu itanura rishyuha cyane ry’inganda ndetse n’ahantu nyaburanga ho gukora ibikoresho bya semiconductor, hari igice cy’ingenzi gisa n’aho gisanzwe ariko cy’ingenzi - silicon carbide square beam. Ntabwo gikurura amaso nk’ibicuruzwa bya terminal, ariko kubera imikorere yacyo idasanzwe, cyabaye "umurinzi utagaragara" w’inganda nyinshi zikora ibikoresho byo mu rwego rwo hejuru. Uyu munsi, mu mvugo yoroheje, turabagezaho iki gice gishya cy’ibikoresho gifite ubuhanga budasanzwe.
Akamaro k'ingenzi kaimitako ya karubide ya silikoniikomoka ku miterere yihariye ya silicon carbide yayo y'ibikoresho fatizo. Iki gikoresho, kigizwe na silicon na karuboni, gifite imitungo mike cyane kandi ahanini gikorerwa mu nganda. Ubukomere bwacyo ni ubwa kabiri nyuma ya diyama kandi bukomeye cyane kurusha ibikoresho gakondo by'icyuma. Nyuma yo gutunganywa mu buryo bw'urukiramende, cyongera inyungu zacyo ku bikoresho kandi kikaba "umuntu ukomeye" ushobora kwihanganira ibidukikije bikomeye.
Ubudahangarwa bw'ubushyuhe bwinshi ni umwihariko w'imiringa ya kare ya silikoni. Mu matanura y'inganda ku gipimo cya dogere selisiyusi ibihumbi, ibyuma bisanzwe byamaze koroha no kwangirika, mu gihe imiringa ya kare ya silikoni ishobora kugumana imiterere yayo neza kandi ntizahinduka bitewe n'ubushyuhe bwinshi. Ubu bushobozi bwo "guhangana n'ubushyuhe bwinshi" butuma iba amahitamo meza mu bihe bisaba ibikorwa by'ubushyuhe bwinshi, hatabayeho gusimburwa kenshi, bigabanya cyane igihombo cy'umusaruro.
Uretse kuba idashobora gushyuha cyane, "idashobora gukora" igaragarira no mu kudashyuha no gukomera cyane. Mu nganda, ntibishoboka guhura n'ibintu byangiza nka aside na alkali. Ubuso bw'imirimbo ya silikoni carbide kare bushobora gukora firime irinda ihamye kugira ngo irwanye ibitero bitandukanye bya shimi kandi ntibuzangiza cyangwa ngo bwangirike. Muri icyo gihe, ni ubworoheje ariko bufite ubushobozi bukomeye bwo gutwara imizigo. Nk'imiterere y'ibikoresho, ishobora gutuma bishyigikirwa neza nta kongeramo umutwaro mwinshi ku bikoresho byose, kandi ishobora no kugabanya ikoreshwa ry'ingufu.
Kuva ku byuma bishyigikira umuriro wa keramike, kugeza ku byuma by’ingenzi bishyigikira gukora semiconductor, ndetse no ku bikoresho birwanya ubushyuhe bwinshi mu bijyanye n’ingufu nshya, imirasire ya silikoni carbide iboneka mu nganda nyinshi z’ingenzi. Ntabwo ifite imiterere igoye, ariko ikemura ibibazo ibikoresho gakondo bidashobora guhangana nabyo mu buryo buhamye, ikaba inkingi ikomeye mu nzira yo kuvugurura inganda zigezweho.
Bitewe n’iterambere rihoraho ry’ikoranabuhanga rishya ry’ibikoresho, ikoreshwa ry’imitako ya silikoni karuboni riracyari kwiyongera. Iyi "nkunga ikomeye" ihishe irimo gufasha bucece iterambere ry’inganda zitandukanye mu buryo bwo kuramba, guhamye no kwizerwa, ikaba imbaraga zitagaragara ariko z’ikoranabuhanga.
