From NEMO1D and NEMO3D to OMEN: Moving towards atomistic 3-D quantum transport in nano-scale semiconductors

Lessons learned in 15 years of NEMO development starting from quantitative and predictive resonant tunneling diode (RTD) to multi-million atom electronic structure modeling and the path for OMEN are laid out. The recent OMEN capabilities enable realistically large 3D atomistic nano-scale device simulation.
