For the highest temperature variety of 600�?100 °C, the lower neutron scattering length density at high temperature is reliable with a silicon-wealthy, liquid surface period equivalent to molten nickel silicides and copper. This liquid catalyst layer encourages the liquid-stage epitaxial growth of the graphene layer by precipitating the excess carbon https://www.facebook.com/permalink.php?story_fbid=pfbid0oJyoGo3iEHm1UAkBXLBnWoetbR8bgeg7esebNA4xNUVhoyXwTB5Q7K4h9phDeBxwl&id=61562415773754&__cft__[0]=AZWF4bRKniRoPrba2rxYRja7Y3btnitvj8yfpAFzaKwa2JFxamXFamFW0fSURq4DMx2zrg9Kxt0r7xrKl3nahUovixq5RThpaZp-tz9Ojpeyz5-ZUOcTrUCF8LrAqh_9eLdgjvdgxjzCbVJLnn40nyuqb1ypXrCCpp6bD5JAiGnc4H6GL216EGB-rdzFNCvtzaLy0h2vpS522QI0fwrHkf_j&__tn__=%2CO%2CP-R
