Cov txheej txheem semiconductors yog cov tsim ntawm ib hom ntawm atoms, xws li silicon (Si), germanium (Ge), thiab tin (Sn) hauv kab IV thiab selenium (Se) thiab tellurium (Te) nyob rau hauv kab VI ntawm lub periodic table. Txawm li cas los xij, muaj ntau yam khoom siv hluav taws xob, uas muaj ob lossis ntau lub ntsiab lus.
Yam khoom twg yog cov khoom siv hluav taws xob?
Semiconductors yog cov khoom siv uas muaj cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob (feem ntau cov hlau) thiab cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob (xws li cov ceramics feem ntau). Semiconductors tuaj yeem yog cov khoom ntshiab, xws li silicon lossis germanium, lossis cov tebchaw xws li gallium arsenide lossis cadmium selenide.
xya yam khoom semiconductor yog dab tsi?
Hom khoom siv semiconductor
- Group IV elemental semiconductors, (C, Si, Ge, Sn)
- Group IV compound semiconductors.
- Group VI elemental semiconductors, (S, Se, Te)
- III-V semiconductors: Crystallizing nrog qib siab ntawm stoichiometry, feem ntau tuaj yeem tau txais ob hom n-hom thiab p-type.
Yuav ua li cas lub ntsiab lus feem ntau yuav yog semiconductor?
Silicon yog cov khoom siv feem ntau siv los ua cov khoom siv hluav taws xob. Silicon yog cov hlau uas muaj nyob hauv cov xuab zeb thiab siv los ua iav. Germanium, uas yog ncaj qha hauv qab silicon ntawm lub sij hawm lub sij hawm, kuj yog siv nyob rau hauv hluav taws xob semiconductors.
Qhov twg ntawm cov ntsiab lus hauv qab no yog ib qho hlau?
Key Takeaways: Semimetals lossis Metalloids
Feem ntau, cov semimetals lossis metalloids tau teev npe boron, silicon, germanium, arsenic, antimony, tellurium, thiab polonium. Qee cov kws tshawb fawb tseem xav txog tennessine thiab oganesson ua metalloids.
