At the highest temperature selection of 600�?100 °C, the minimal neutron scattering length density at high temperature is steady with a silicon-wealthy, liquid surface phase equivalent to molten nickel silicides and copper. This liquid catalyst layer promotes the liquid-phase epitaxial growth of the graphene layer by precipitating the surplus carbon https://www.facebook.com/permalink.php?story_fbid=pfbid0PfJSgXDVkQabHKSo1oGp5zuGi6N2vqx3DJ6Q1YKGnZ6JwvNzQkKHc7pnzSc2sujfl&id=61562415773754&__cft__[0]=AZXukXIoLbo_ZTZOL6q7YPeFHfYkKjXGu4w1CjpO1lgUOCe-kYWlnbbUKAMPrvdbXHM_5mmT0AhKwyBjuhL104IibQh4G9acb14e4TTjG3hpiYz6npjyZrC2JW9EZfMookzntzDUd8pe6CYizMBjtHtdlwpp_FCmT_G-qAv_DYRvoEYv0y8HGQ_ifaeCZg8pegBuds0HirYwPYYLSXfe43Dq&__tn__=%2CO%2CP-R
