Novel first-principle simulations of 3D atomistic structure

Modeling approaches in computational electronics have become increasingly driven by the need of more fundamental and comprehensive understanding of the nanoscale physics of system only through knowledge of the constituent atoms. First principle calculation, which [...]

Linear scaling techniques for first-principle calculations of large nanowire devices

Zhang D., Polizzi E., University of Massachusetts, FR

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 [...]

Computational Challenges in Nanoscale Device Modeling

Polizzi E., Sameh A., Sun H., Purdue University, US

The development of new simulation tools is critical for the exploration of quantum transport in nanoscale devices. Such simulation is commonly performed by solving self-consistently the transport problem using The Non-Equilibrium Green's Functions (NEGF) formalism [...]
