Ib yam khoom (xws li arsenic, antimony, lossis tin) uas nws cov khoom yog nruab nrab ntawm cov hlau thiab cov khoom tsis yog hlau lossis semiconductors. 'Kev cais lawv yog metalloids lossis semimetals. '
Semimetal txhais li cas?
: ib yam khoom (xws li arsenic) muaj cov khoom hlau hlau hauv qhov qis dua thiab tsis tuaj yeem.
Koj paub li cas ib lub semimetal?
Nyob rau hauv ib lub semimetal, lub hauv qab ntawm cov kab hluav taws xob feem ntau nyob hauv qhov sib txawv ntawm qhov chaw sib txawv (ntawm qhov sib txawv k-vector) dua li sab saum toj ntawm valence band. Ib tug tuaj yeem hais tias semimetal yog ib qho semiconductor nrog qhov tsis zoo ntawm qhov tsis ncaj qha bandgap, txawm hais tias lawv tsis tshua tau piav qhia hauv cov ntsiab lus.
YPuas yog semimetal thiab metalloid tib yam?
Anne Marie Helmenstine, Ph. D. Nruab nrab ntawm metals thiab nonmetals yog ib pawg ntawm cov ntsiab lus hu ua semimetals lossis metalloids, uas yog cov khoom uas muaj cov khoom nruab nrab ntawm cov hlau thiab nonmetals. … Metalloids muaj cov khoom semiconductor thiab tsim amphoteric oxides.
Semi hlau thiab piv txwv yog dab tsi?
Feem ntau, cov semimetals lossis metalloids tau teev npe boron, silicon, germanium, arsenic, antimony, tellurium, thiab poloniumQee cov kws tshawb fawb kuj xav txog tennessine thiab oganesson ua metalloids. Metalloids yog siv los ua semiconductors, ceramics, polymers, thiab roj teeb.
