The nextnano³ solver#
The nextnano³ tool is the predecessor of nextnano++.
Features of nextnano³ include:
includes group IV materials (Si, Ge, SiGe), all III-V materials, II-VI materials and its ternaries as well as lattice-matched quaternaries. The nitride and II-VI materials are available in the zinc blende and wurtzite crystal structure.
flexible structures and geometries (1D, 2D and 3D)
quantum mechanics based on single-band and multi-band \(\mathbf{k} \cdot \mathbf{p}\) 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
