Muab piv rau Pob Zeb Diamond, Cov kws tshawb fawb ua ke cov khoom siv tawv nrog lub zog siab ceev

Ib pab neeg thoob ntiaj teb coj los ntawm University of Edinburgh's Center for Extreme Conditions Science tau tsim cov pa roj carbon monoxide thiab nitrogen precursors los tsim carbonitride hlau, uas yog nruj dua li cov cubic boron nickel hlau uas twb muaj lawm, uas yog thib ob tsuas yog pob zeb diamond hauv hardness.

Cov kws tshawb fawb tau lees paub lub peev xwm ntawm carbonitride hlau thaum ntxov li xyoo 1980 thiab pom tias nws muaj ntau yam khoom zoo xws li kev kub ntxhov, tab sis ua rau cov ntaub ntawv no yog lwm qhov teeb meem, thiab txog tam sim no, tsis tau muaj ntau yam kev kawm tiav ntawm kev sib txuas.

Cov kws tshawb fawb tau ua tiav qhov kev ua tau zoo los ntawm kev tso ntau hom carbon-nitrogen precursors nyob rau hauv siab ntawm 70-135 gigapascals (sib npaug rau ib lab lub sij hawm atmospheric siab) thaum cua sov rau 1500 degree (2732 degree F).

 

Kev tsom xam pom tau tias peb cov khoom sib xyaw ua ke carbon nitride muaj cov qauv tsim nyog rau cov khoom siv superhard, thiab cov kws tshawb fawb tau xav tsis thoob thaum pom tias peb lub tebchaw khaws lawv cov khoom superhard tom qab txias thiab rov qab mus rau qhov chaw siab.

Pab neeg no ntseeg hais tias qhov kev sib tawg ua rau txoj hauv kev rau kev siv nrog rau kev tiv thaiv txheej rau lub tsheb thiab lub dav hlau, cov cuab yeej txiav cov cuab yeej muaj zog thiab cov cuab yeej photodetectors.
