for the simulation of electronic and optoelectronic semiconductor nanodevices

We develop powerful tools for the simulation of nanostructures.nd opWe develop powerful tools for the simulation of nanostructures.

Applications include nanotransistors, LEDs, laser diodes, quantum dots, nanowires, quantum cascade lasers, HEMTs, photodetectors and solar cells.

Due to the continuing scaling of semiconductor electronics, quantum physical effects are gaining importance and fundamentally challenge industry with respect to simulation and design. Our unique selling proposition is an advanced physical method for the calculation of the quantum mechanical properties of an arbitrary combination of geometries and materials.

We essentially offer five software tools.

nextnanomat
Front End & Workflow Manager
nextnanomat provides the graphical user interface (GUI) for the nextnano++, nextnano³, nextnano.NEGF and nextnano.MSB software.
nextnano++
Our Schrödinger-Poisson-Current solver written in C++.
nextnano³
Our Schrödinger-Poisson-Current solver written in Fortran.
nextnano.NEGF
Our NEGF code for quantum transport in e.g. quantum cascade lasers (QCLs) and resonant tunneling diodes (RTDs) based on the nonequilibrium Green's function method (NEGF).
nextnano.MSB
Our NEGF code for quantum transport in e.g. quantum cascade lasers (QCLs) and resonant tunneling diodes (RTDs) based on the multi-scattering Büttiker probe model (MSB).
Whether you want to use nextnano++ or nextnano³ is up to you. Choose your flavor!
