WebSince the first report of the Shubnikov–de Haas effect in a 2D system by Fowler et al. (1966a, 1966b) for Si metal-oxide-semiconductor field-effect transistor (Si-MOSFET), many studies have been performed on the quantum transport phenomena in 2D systems. These have led to the discovery of the quantum Hall effect. WebMay 2, 2013 · The mechanical stability of graphene as temperature rises is analyzed based on three different self-consistent phonon (SCP) models. Compared with three-dimensional (3-D) materials, the critical temperature T i at which instability occurs for graphene is much closer to its melting temperature T m obtained from Monte Carlo simulation (T i ≃ 2T m, …
