Chifukwa chiyani SiGe imagwiritsidwa ntchito?

SiGe powder, amadziwikanso kutisilicon germanium ufa, ndizinthu zomwe zalandira chidwi kwambiri pazaukadaulo wa semiconductor.Nkhaniyi ikufuna kufotokoza chifukwa chakeSiGeamagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana ndikufufuza zinthu zake zapadera ndi zabwino zake.

Silicon germanium ufandi chinthu chophatikizika chopangidwa ndi silicon ndi ma atomu a germanium.Kuphatikiza kwa zinthu ziwirizi kumapanga chinthu chokhala ndi zinthu zochititsa chidwi zomwe sizipezeka mu silicon yoyera kapena germanium.Chimodzi mwa zifukwa zazikulu zogwiritsira ntchitoSiGeKugwirizana kwake kwakukulu ndi matekinoloje opangidwa ndi silicon.

KuphatikizaSiGepazida zokhala ndi silicon zimapereka maubwino angapo.Ubwino umodzi waukulu ndi kuthekera kwake kusintha zinthu zamagetsi za silicon, potero kuwongolera magwiridwe antchito azinthu zamagetsi.Poyerekeza ndi silicon,SiGeimakhala ndi ma elekitironi apamwamba komanso kuyenda kwa dzenje, zomwe zimalola kuti ma elekitironi aziyendera mwachangu komanso kuthamanga kwa chipangizocho.Katunduyu ndiwopindulitsa makamaka pamapulogalamu apamwamba kwambiri, monga makina olumikizirana opanda zingwe komanso mabwalo ophatikizika othamanga kwambiri.

Kuonjezera apo,SiGeali ndi mpata wocheperako kuposa silicon, womwe umalola kuyamwa ndi kutulutsa kuwala bwino.Katunduyu amapangitsa kukhala chinthu chofunikira pazida za optoelectronic monga ma photodetectors ndi ma light-emitting diode (LEDs).SiGeilinso ndi matenthedwe abwino kwambiri, omwe amalola kuti azitha kutentha bwino, ndikupangitsa kuti ikhale yabwino pazida zomwe zimafuna kuwongolera bwino kwamafuta.

Chifukwa chinaSiGeKugwiritsiridwa ntchito kofala ndi kugwirizanitsa kwake ndi njira zomwe zilipo kale zopangira silicon.SiGe powderitha kusakanikirana mosavuta ndi silicon ndikuyika pagawo la silicon pogwiritsira ntchito njira zopangira semiconductor monga chemical vapor deposition (CVD) kapena molecular beam epitaxy (MBE).Kuphatikizana kosasunthika kumeneku kumapangitsa kuti zikhale zotsika mtengo komanso zimatsimikizira kusintha kosavuta kwa opanga omwe akhazikitsa kale malo opangira silicon.

SiGe powderimatha kupanganso silicon yokhazikika.Kupsyinjika kumapangidwa mu silicon wosanjikiza ndikuyika wosanjikiza woonda waSiGepamwamba pa silicon gawo lapansi ndiyeno kusankha kuchotsa maatomu germanium.Mtundu uwu umasintha mawonekedwe a gulu la silicon, kupititsa patsogolo mphamvu zake zamagetsi.Silicon yolumikizidwa yakhala gawo lofunikira kwambiri pama transistors ochita bwino kwambiri, zomwe zimapangitsa kuthamanga kwachangu komanso kugwiritsa ntchito mphamvu pang'ono.

Kuphatikiza apo,SiGe powderali ndi ntchito zosiyanasiyana m'munda wa zida za thermoelectric.Zipangizo zamagetsi zamagetsi zimasintha kutentha kukhala magetsi komanso mosemphanitsa, zomwe zimapangitsa kuti zikhale zofunika kwambiri pakugwiritsa ntchito monga magetsi opangira magetsi ndi kuziziritsa.SiGeali ndi machulukidwe apamwamba amafuta komanso magetsi osinthika, omwe amapereka zinthu zabwino kwambiri zopangira zida zogwiritsira ntchito bwino za thermoelectric.

Pomaliza,SiGe powder or silicon germanium ufaili ndi maubwino osiyanasiyana ndikugwiritsa ntchito paukadaulo wa semiconductor.Kugwirizana kwake ndi njira zomwe zilipo kale za silicon, zinthu zabwino kwambiri zamagetsi ndi matenthedwe amatenthedwe zimapangitsa kukhala chinthu chodziwika bwino.Kaya kuwongolera magwiridwe antchito a mabwalo ophatikizika, kupanga zida za optoelectronic, kapena kupanga zida zamagetsi zamagetsi zamagetsi,SiGeikupitiriza kutsimikizira kufunika kwake monga zinthu zambiri.Pamene kafukufuku ndi luso lamakono likupita patsogolo, tikuyembekezaSiGe ufakutenga gawo lofunikira kwambiri pakukonza tsogolo la zida za semiconductor.
