Electronic structure and quantum conductance of nanostructures
… approach to study the electronic structure and quantum conductance of realistic nanoscale materials. Electron transport at the nanometer scale involves phenomena which are beyond the realm of classical transport theory: the wave character of the electrons becomes central, and the Schrddinger …

Large Scale Simulations of Conduction in Carbon Nanotube Networks
… and on an industrial scale. Their electrical conductance, however, is orders of magnitude lower than expected and the origin of this poor performance is not well understood. In these wires, the CNTs form a conducting network whereby current flows along individual CNTs and also between the …
