nextnano++ software for semiconductor nanodevices

nextnano++ software can run on nextnanomat, which is a GUI (graphical user interface) for editing input files (ASCII, XML), organizing simulations and submitting jobs (directly or via a batch list), as well as visualizing simulation results. Parallel job execution is supported on multi-core CPUs automatically.

nextnanomat is customized to work with the following software:

nextnano³

nextnano++

nextnano.MSB

nextnano.QCL

However, it is general enough to be adjusted to any TCAD or scientific software that reads in an ASCII file, passes this ASCII file to an executable, and visualizes its 1D, 2D and 3D results.

nextnanomat can be used as a visualization software for 1D, 2D and 3D results (e.g. somewhat "similar" (but much simpler) than Origin, gnuplot, Compaq Array Viewer, Intel Array Viewer).

The focus lies on quick visualization rather than on professional editing of graphs.

nextnano++ features:

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 k.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

various input file examples and material database
