2. nextnano++¶
nextnano++ is a Schrödinger-Poisson-current solver and simulates quantum wells, quantum wires, quantum dots, … nextnano++ (written in C++) is the successor of the nextnano³ code (written in Fortran).
nextnano++ features 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 nonequilibrium, calculation of current close to equilibrium (semi-classical)
magnetic fields
