Muaj peb hom kev siv lead ua tsis zoo:
- Point defects.
- kab defects.
- Planar defects.
Dab tsi yog hom lattice imperfections pom nyob rau hauv crystals chav kawm 12?
Schottky defect muaj feem ntau hauv cov khib nyiab ionic uas cations thiab anions yog qhov sib piv loj thaum Frenkel qhov tsis xws luag muaj feem ntau hauv cov khib nyiab ionic uas cations thiab anions muaj qhov sib txawv loj hauv Lawv qhov loj me ionic.
Yuav ua li cas yog qhov txawv ntawm cov khoom siv hauv cov iav siv lead ua?
- Point defects (vacancy, interstitial defects, hloov pauv tsis xws luag)
- kab defect (ntsia hlau dislocation, ntug dislocation)
- defects defects (khoom nto, grain ciam teb) …
- Hloov pauv - ib lub atom hloov los ntawm ntau hom atom.
- Interstitial - ntxiv atom yog ntxig rau hauv cov qauv lattice ntawm a.
Yuav ua li cas yog hom crystal imperfections?
Kev faib tawm ntawm crystal imperfections. Crystal imperfections tuaj yeem muab faib ua plaub yam yooj yim raws li hom kev tsis xws luag thiab nws qhov loj me. Lawv yog point defects (0-dimensional), kab defects (1-dimensional), defects nto (2-dimensional) thiab ntim defects (3-dimensional).
Puas muaj pes tsawg hom kev tsis xws nyob hauv crystal piav?
Kev tsis zoo lossis tsis zoo hauv cov khoom siv crystalline tuaj yeem muab faib ua plaub pawg uas yog kab tsis xws luag,point defects, volume defects thiab nto defects. Keeb kwm, crystal point defects yog thawj zaug saib nyob rau hauv ionic crystals, tsis nyob rau hauv cov hlau crystals uas yog ntau yooj yim.
