Pob zeb diamond yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws paub, yog pob tshab rau lub teeb, thiab tsis ua hluav taws xob kiag li. Graphite yog mos, grey, thiab tuaj yeem ua hluav taws xob zoo. Xws li cov khoom sib txawv, los ntawm ob yam khoom uas tsim los ntawm tib hom atoms!
Peb qhov txawv ntawm pob zeb diamond thiab graphite yog dab tsi?
Pob zeb diamond yog ib qho hluav taws xob insulator thaum graphite yog ib qho hluav taws xob zoo. Pob zeb diamond feem ntau yog pob tshab, tab sis graphite yog opaque. Pob zeb diamond yog pom tseeb tias muaj nuj nqis ntau dua li graphite. Graphite yog pheej yig heev uas nws yog siv los ua xaum xaum.
Dab tsi yog qhov txawv ntawm cov qauv ntawm pob zeb diamond thiab graphite?
Pob zeb diamond: txhua carbon atom bonds rau 4 lwm carbon atoms, WHILST, Graphite: txhua carbon atom bonds rau 3 lwm carbon atoms. Yog li, pob zeb diamond bears ntau dua ntawm cov qauv tetrahedral, whereas graphite siv cov txheej txheem. Lub xub ntiag ntawm cov khaubncaws sab nraud povtseg txhais tau hais tias cov atoms tuaj yeem swb ib leeg yooj yim.
Dab tsi yog qhov sib txawv thiab zoo sib xws ntawm graphite thiab pob zeb diamond?
Pob zeb diamond muaj cov qauv tetrahedral thiab yog cov khoom siv nyuaj tshaj plaws rau txiv neej. Muaj muaj zog covalent bonds ntawm carbon atoms thiab txhua carbon atom yog bonded rau 4 lwm carbon atomsGraphite muaj ib tug hexagonal txheej txheej thiab txhua cov pa roj carbon yog bonded los ntawm muaj zog covalent bonds rau 3 lwm carbon atoms.
Dab tsi yog pob zeb diamond thiab graphite?
Graphite yog ib qho zoo ntawm hluav taws xob tab sis lub pob zeb diamond tsis yog. Yog li, tsuas yog tus yam ntxwv ntawm ob qho tib si yog tsim los ntawm carbon atomsuas muaj qhov tseeb atomic loj uas tsis hloov nrog daim ntawv.

Leej twg yug pob zeb yog pob zeb diamond?
Lub pob zeb diamond yog lub pob zeb yug ib txwm muaj ntawm Lub Plaub Hlis thiab tuav lub ntsiab lus tseem ceeb rau cov neeg yug hauv lub hli, xav muab cov neeg hnav nrog kev sib raug zoo zoo dua thiab nce lub zog sab hauv. Kev hnav pob zeb diamond yog qhia kom coj tau lwm yam txiaj ntsig xws li kev sib npaug, kev pom tseeb thiab kev nplua nuj .
Puas lub plawv ntaus pob zeb diamond hauv pob zeb?
Thaum kev sib tw raug siv, feem ntau cov rooj sib tham yog: Cov tsiaj ntawv xaj: cov koom haum (qis tshaj), ua raws li pob zeb diamond, lub siab, thiab cov pob zeb (siab tshaj) . Dab tsi ntaus dab tsi hauv Spades? Cov ntawv teev lus hauv txhua qib qib siab tshaj mus rau qis tshaj:
Puas yog pob zeb diamond yog pob zeb lossis pob zeb?
pob zeb diamond, ib pob zeb muaj li ntawm cov pa roj carbon ntshiab. Nws yog qhov nyuaj tshaj plaws uas tshwm sim tau paub; Nws kuj yog lub pob zeb nrov tshaj plaws . Puas yog pob zeb diamond yog hom pob zeb? Background. Lub pob zeb diamond yog qhov nyuaj tshaj plaws ntuj paub.
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
