Products
We essentially offer five software tools.
- nextnanomat
Front End & Workflow Manager
nextnanomat provides the graphical user interface (GUI) for the nextnano++, nextnano³, nextnano.QCL and nextnano.MSB software. - nextnano++
Our Schrödinger-Poisson-Current solver written in C++. - nextnano³
Our Schrödinger-Poisson-Current solver written in Fortran. - nextnano.QCL
Our NEGF code for quantum cascade lasers (QCLs) written by Thomas Grange based on the nonequilibrium Green’s function method (NEGF).
Features
next generation 3D nano device simulator
The nextnano++ and nextnano³ software are simulators 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 nonequilibrium, calculation of current close to equilibrium (semi-classical), ballistic transport
- magnetic field
- BIO-nextnano³
Semiconductors connected to an electrolyte solution (Poisson-Boltzmann equation)
