Study on the Electronic Transport Properties of Zigzag GaN Nanotubes

摘要：

The electronic transport properties of zigzag GaN nanotubes (n, 0) (4≤ n ≤9) have been calculated using the density functional theory and nonequilibrium Greens functions method. Firstly, the density functional theory (DFT) is used to optimize and calculate the electronic structure of GaNNTs (n, 0) (4≤ n ≤9) . Secondly, DFT and non-equilibrium Green function (NEGF) method are also used to predict the electronic transport properties of GaNNTs twoprobe system. The results showed: there is a corresponding relation between the electronic transport properties and the valley of state density of each GaNNT. In addition, the volt-ampere curve of GaNNT is approximately linear.
