Electronic transport in two-dimensional graphene
A broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature-dependent carrier transport in doped or gated graphene structures is provided. A salient feature of this review is a critical comparison between carrier transport in graphene and in two-dimensional semiconductor systems (e.g., heterostructures, quantum wells, inversion la...
متن کاملSemiclassical theory for transmission through open billiards: convergence towards quantum transport.
We present a semiclassical theory for transmission through open quantum billiards which converges towards quantum transport. The transmission amplitude can be expressed as a sum over all classical paths and pseudopaths which consist of classical path segments joined by "kinks," i.e., diffractive scattering at lead mouths. For a rectangular billiard we show numerically that the sum over all such...

A semiclassical transport model for two-dimensional thin quantum barriers
We present a two-dimensional time-dependent semiclassical transport model for mixed state scattering with thin quantum films. The stationary Schrödinger equation is solved in the quantum barrier to obtain the scattering coefficients used to supply the interface condition that connects two classical domains. The solution in the classical regions is solved using a particle method and interface co...
متن کاملA Semiclassical Transport Model for Thin Quantum Barriers
We present a one-dimensional time-dependent semiclassical transport model for mixed state scattering with thin quantum barriers. The idea is to solve a stationary Schr6dinger equation in the thin quantum barrier to obtain the scattering coefficients, and then use them to supply the interface condition that connects the two classical domains. We then build in the interface condition to the numer...
