for the simulation of electronic and optoelectronic semiconductor nanodevices

We develop powerful tools for the simulation of nanostructures.

Applications include nanotransistors, LEDs, laser diodes, quantum dots, nanowires, quantum cascade lasers, HEMTs, infrared detectors 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.
