摘要：

In order to simplify the numerical investigation of carrier transport in nanodevices without jeopardizing the rigor of a full quantum mechanical treatment, we have exploited an existing variational principle to solve self-consistently Poisson's equation and Schrodinger's equation as well as an appropriate transport equation within the scope of the generalized local density approximation (GLDA). In this work, as a benchmark, we have applied our approach to compute the ballistic current density and electron concentration in a Si nanowire.
