Wrinkling of graphene because of the thermal expansion mismatch between graphene and copper
Well-defined bundles of wrinkles are observed on the graphene-covered copper by using atomic force microscopy after chemical vapor deposition process. Their numerical analyses are performed by employing a set of formula ...
The effects of acid pretreatment and surface stresses on the evolution of impurity clusters and graphene formation on Cu foil
(ELSEVIER SCIENCE BV, 2017-12)
In this study, the effects of acid pretreatment together with the surface stresses are studied systematically to control the densities of Si and Ca based impurities on the surface and to understand their effects on the ...
