Miller indices yog siv txhawm rau qhia cov lus qhia thiab dav hlau. Cov kev taw qhia thiab cov dav hlau no tuaj yeem yog hauv lattices lossis hauv cov muaju. Tus naj npawb ntawm qhov ntsuas yuav sib phim nrog qhov ntev ntawm lub lattice lossis cov siv lead ua.
Tus yam ntxwv tseem ceeb ntawm Miller indices yog dab tsi?
Qhov tseem ceeb ntawm Miller Indices:
- Ib lub dav hlau uas sib npaug rau ib qho ntawm cov kev sib koom ua ke muaj qhov cuam tshuam ntawm infinity (∞) thiab yog li ntawd, Miller Performance index rau qhov axis yog xoom.
- Txhua qhov sib npaug sib npaug sib npaug ntawm cov dav hlau uas muaj kev taw qhia tshwj xeeb muaj tib tus lej ntsuas (h k I).
Koj sawv cev rau Miller li cas?
1.2: Miller Indices (hkl)
- Kauj Ruam 1: Txheeb xyuas qhov cuam tshuam ntawm x-, y- thiab z- axes. …
- Kauj Ruam 2: Qhia cov kev cuam tshuam hauv kev sib koom ua ke ntawm feem. …
- Kauj Ruam 3: Siv cov kev cuam tshuam ntawm cov feem cuam tshuam. …
- Lwm yam piv txwv.
Puas muaj lub dav hlau nrog Miller indices 020)? Puas yog qhov no tsis zoo ib yam li 010 lub dav hlau raws li peb qhia tawm ntau yam hauv Miller indices?
Yes, nyob rau hauv Miller indices peb feem ntau qhia tawm qhov ntau yam. Piv txwv tias peb xav txog qhov yooj yim cubic siv lead ua, ces alternate (020) dav hlau yuav tsis muaj atoms nyob rau hauv lawv!
Vim li cas tag nrho cov dav hlau sib npaug sib luag muaj tib yam Miller indices?
Vim tias cov lattice silicon zoo tib yam raws li txhua qhov ntawm peb lub cubic axes, ntau lub dav hlauyog sib npaug. Piv txwv li, lub (100), (010), thiab (001) dav hlau, uas yog orthogonal rau x, y, thiab z coordinate axes, yog sib npaug ntawm lub cev.
