next generation 3D nano device simulator







nextnano³ is a simulator for calculating, in a consistent manner, the realistic electronic structure of three-dimensional heterostructure quantum devices under bias and its current density close to equilibrium. The electronic structure is calculated fully quantum mechanically, whereas the current is determined by employing a semiclassical concept of local Fermi levels that are calculated self-consistently.

Simulating quantum dots, quantum wires, RTDs, MOSFETs, HEMTs, etc.

• includes group IV materials (Si, Ge, SiGe), all III-V and II-VI materials and its ternaries as well as lattice-matched quaternaries; the nitrides and the II-VI materials are available in the zincblende and wurtzite crystal structure
  
• flexible structures and geometries (1D, 2D and 3D)
• fully quantum mechanically, based on the 8-band k.p model within a finite differences grid
• includes strain, piezo and pyroelectric charges
• growth directions along [001], [011], [111], [211], ... in short along any crystallographic direction
• equilibrium and non-equilibrium, calculation of current close to equilibrium (semi-classical), ballistic transport
• magnetic field
• optical absorption
• BIO-nextnano³
