The paper employs molecular dynamics simulations for studying friction in graphene channels of height less than 1 nanometer as a function of graphene misalignment. The work is a collaborative work with University of Waterloo, and Dr. Enrique Wagemann (my former postdoc advisee and currently a faculty member in University of Concepcion, Chile) is the lead author of the paper. This is Enrique’s 3rd paper with me.
