Abstract Contact resistance, as one of the main parameters that limits the performance of graphene-based transistors, is highly dependent on the metal-graphene contact fabrication processes. These processes are investigated and the corresponding resi

Based on the photocurrent model, terahertz (THz) radiation generation in three-color (fundamental ($$\omega $$), second-harmonic ($$2\omega $$), and third-harmonic ($$3\omega $$)) laser-induced air plasma is studied using particle in cell simulation.
