Pob zeb diamond tau muab faib rau hauv ib qho muaju, ua kom muaju, thiab polychenals raws lawv cov qauv sab hauv. Nyob rau hauv Suav cov ntaub ntawv kev tshawb fawb hauv zej zog, cov lus "polycrystals, aggregated muaju, thiab cov microcrystals" yog siv xoob. Polycrystals xa mus rau ib qho muaju xwb. Txawm hais tias muaj cov muaju sib xyaw ua ke kuj yog ib hom polycystal, lawv feem ntau suav cov muaj tshuaj lom neeg ua ke los ntawm kev txiav txim siab rau ib leeg muaju ua ke. Cov microcrystals xa mus rau ib qho kev cai tshwj xeeb ntawm cov muaj cov muaju sib xyaw ua ke nyob rau hauv uas cov cheeb tsam geometric ntawm cov crystalline thaj chaw muaj tsawg heev, feem ntau hauv cov micrometer ntau.
Pob zeb diamond ib qho muaju yog feem ntau faib raws li lawv cov khoom kho. Pob zeb diamond yog feem ntau categorized rau hom I thiab hom II. Lub xub ntiag ntawm nitrogen thiab coron li impurities nyob rau hauv lub pob zeb diamond nyob rau hauv lub pob zeb diamond incly cais ntawm hom I thiab hom II. Piv txwv li, hom kuv pob zeb diamond muaj cov nitrogen impurities. Nitrogen impurities tau dav tam sim no nyob rau hauv ntuj thiab hluavtaws diamonds thiab ntau yam cuam tshuam rau lawv lub cev thiab tshuaj. Pob zeb diamond muaj cov nitrogen impurities tau muab faib ntxiv mus rau hom iaa, muaj cov khub nitrogen. Ntaus Iob, muaj plaub pawg ntawm cov atoms; thiab ntaus ib, muaj nitrogen dawb.
Pob zeb diamondized nyob rau hauv kev kub siab thiab kub feem ntau tsis raug rau kev tswj hwm kev txwv thaum lub sijhawm thauj khoom, ua rau muaj me ntsis ntsuab huws. Cov pob zeb diamond no yog hom IB lub pob zeb diamond. Hom IA pob zeb diamond yog nitrogen-dawb thiab muaj cov nitrogen thiab lwm yam impurities. Vim tias lawv zoo heev thermal conductivity, hom iia pob zeb diamond yog feem ntau siv hauv cov khoom siv hluav taws xob hauv lub xeev thiab cua sov. Loj-Loob Hom Iia cov pob zeb diamond tuaj yeem yog cov khoom siv dag ntxias, thiab lawv muab cov qauv pheej yig rau cov khoom sib txuas lus rau lwm cov ntaub ntawv.
Hom Iib pob zeb diamond muaj tib lub thaj chaw tib yam li hom IA pob zeb diamond. Kwv yees li ib-txhiab ntawm hom II pob zeb diamond yog hom Iib, nthuav tawm cov khoom lag luam sicemeror. Hom Iib pob zeb diamond muaj cov bandgap dav thiab tiv taus qhov kub siab. Lawv cov cua sov zoo heev disspation, tshuab siv tshuab, thiab corrosion tsis kam cia lawv khiav lag luam hauv cov kev mob nyuaj.
