| Abstract: | This paper aims to provide a sound basis to face the challenges in large scale atomistic simulations for applications ranging from material sciences and chemistry to nanoelectronics and bio-nanotechnology. In nanoelectronics, large scale ’ab-initio’ simulations could signi cantly enhance our understanding of nanoscale physics and engineering related issues of materials and transistor devices. At large scale (scale of a transistor), rst-principle atomistic simulations of devices are in need of appropriate ef cient modeling strategies and innovative numerical algorithms. To achieve these goals, first-principle continuum-based modeling and calculations are performed using efficient real-space mesh techniques within the density functional theory and non-equilibrium Green’s function formalism. |
