nextnano++ Documentation

The nextnano++ tool is a Schrödinger-Poisson-current solver and simulates quantum wells, quantum wires, quantum dots, …

Features of nextnano++ include:

• includes group IV materials (Si, Ge, SiGe) and all III-V materials, its ternaries and quaternaries;

• the nitrides are available in the zinc blende and wurtzite crystal structure

• flexible structures and geometries (1D, 2D and 3D)

• fully quantum mechanical electronic structure, based on the 8-band \(\mathbf{k} \cdot \mathbf{p}\) model

• 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)

• magnetic fields
