Yufeng Hao,M. S. Bharathi,Lei Wang,Yuanyue Liu,Hua Chen,Shu Nie,Xiaohan Wang,Harry Chou,Cheng Tan,Babak Fallahazad,H. Ramanarayan,Carl W. Magnuson,Emanuel Tutuc,Boris I. Yakobson,Kevin F. McCarty,Yong-Wei Zhang,Philip Kim,James Hone,Luigi Colombo,Rodney S. Ruoff +19 more
TL;DR: It was found that the presence of surface oxygen could limit the number of nucleation sites and allowed centimeter-scale domains to grow through a diffusion-limited mechanism, and the electrical conductivity of the graphene was comparable to that of exfoliated graphene.
Journal ArticleDOI

Journal ArticleDOI
Pattern formation and nonlinear evolution in alloy surfaces by ion-beam sputtering
TL;DR: In this article, a kinetic Monte Carlo model for sputtering of alloy surfaces is presented, which exhibits morphological ripples and compositional patterns, showing a crossover from an early stage exponential growth to a later stage power-law growth.
Journal ArticleDOI
Molecular simulation of linear octacosane via a CG10 coarse grain scheme.
TL;DR: In this article , a coarse grain scheme (CG10) was developed to reproduce the pivotal phase characteristics of octacosane with highly improved computational efficiency, which is able to reproduce critical structure and property characteristics.
