Theoretical formation of carbon nanomembranes under realistic conditions using classical molecular dynamics
arXiv:2011.00880 · doi:10.1103/PhysRevB.103.115416
Abstract
Carbon nanomembranes made from aromatic precursor molecules are free standing nanometer thin materials of macroscopic lateral dimensions. Although produced in various versions for about two decades not much is known about their internal structure. Here we present a first systematic theoretical attempt to model the formation, structure, and mechanical properties of carbon nanomembranes using classical molecular dynamics simulations. We find theoretical production scenarios under which stable membranes form. They possess pores as experimentally observed. Their Young's modulus, however, is systematically larger than experimentally determined.
