Electrons yog cov khoom tsis zoo ntawm cov atoms. Thaum lawv xav tias yog xoom-dimensional point particles, electrons nyob ib puag ncig los ntawm huab ntawm lwm cov khoom siv hluav taws xob tas li winking hauv thiab tawm ntawm lub neej, qhov tseem ceeb ua raws li ib feem ntawm electron nws tus kheej.
Puas electrons muaj qhov ntev?
electrons muaj huab hwm coj, tab sis ntawm qhov kev daws teeb meem ntawm peb cov thev naus laus zis tam sim no lawv pom tias tsis muaj qhov loj me piv txwv li, lawv zoo li cov ntsiab lus lej.
Puas yog electron 2D lossis 3D?
Nws yog cov roj hluav taws xob uas tsis muaj kev txav mus los hauv ob qhov loj me, tab sis nruj nruj nyob rau hauv peb. Qhov kev kaw nruj no ua rau kom muaj zog ntau ntau rau kev txav mus rau qhov thib peb, uas tuaj yeem tsis quav ntsej rau feem ntau cov teeb meem. Yog li cov electrons zoo li yog ib daim ntawv 2D embedded nyob rau hauv lub ntiaj teb 3D
Puas yog electron 2 seem?
Yog li cov hluav taws xob tshwm sim yog 2D daim ntawv kos rau hauv lub ntiaj teb 3D. Ib qho tseem ceeb tshaj plaws kev txhim kho tsis ntev los no hauv semiconductors, yog qhov ua tiav ntawm cov qauv hauv cov qauv siv hluav taws xob yog qhov tseem ceeb ntawm ob sab (2D).
Puas yog electrons peb-dimensional?
Nyob rau hauv cov ntsiab lus no, physicists hu ib tug electron ib tug "point particle," txhais tau hais tias nws interacts li yog hais tias nws yog tag nrho nyob rau ntawm ib tug taw tes nyob rau hauv qhov chaw thiab tsis kis mus rau ib tug peb- dimensional volume.
