Semiconductors yog cov khoom siv uas muaj cov khoom siv hluav taws xob (feem ntau cov hlau) thiab cov tsis muaj hluav taws xob lossis cov insulators (xws li feem ntau ceramics). Semiconductors tuaj yeem yog cov khoom ntshiab, xws li silicon lossis germanium, lossis cov khoom sib txuas xws li gallium arsenide lossis cadmium selenide.
Yuav siv cov hlau dab tsi hauv semiconductors?
Cov khoom siv semiconductor feem ntau yog silicon, germanium, thiab gallium arsenide. Ntawm peb, germanium yog ib qho ntawm cov khoom siv semiconductor ntxov tshaj plaws. Germanium muaj plaub valence electrons, uas yog electrons nyob rau ntawm lub plhaub sab nraud ntawm lub atom.
Qhov txawv ntawm hlau thiab semiconductor yog dab tsi?
Semiconductors muaj qhov ntsuas kub tsis zoo (lawv nyiam ua kom lawv cov conductivity ntawm qhov kub siab dua), hos cov hlau muaj qhov kub zoo coefficient (lawv conductivity tsawg dua ntawm qhov kub siab dua). … Cov bandgap piv rau ib qho los ntawm semiconductors loj.
Dab tsi yog semiconductor thiab nws hom?
Ib tug semiconductor yog ib hom crystalline khoom uas yog ib nrab ntawm tus neeg xyuas pib thiab cov insulator hais txog hluav taws xob conductivity. Insulators, semiconductors, thiab conductors yog peb hom ntawm cov khoom siv hauv lub xeev.
Dab tsi yog semiconductors ua los ntawm?
Cov khoom siv hluav taws xob feem ntau yog silicon thiab germanium. Silicon yog paub zoo ntawm cov no. Silicon cov ntaub ntawv feem ntauntawm ICs. Feem ntau cov khoom siv semiconductor yog xws li gallium arsenide lossis indium antimonide.
