nextnano++ is a console application
that is run from within the
nextnanomat software (GUI). Alternatively, it can be executed
from the command line. The input file
specifies the device that shall be simulated.
nextnanomat is a convenient graphical user interface
addition, it can visualize 1D, 2D and 3D simulations results.
The input file specifies all properties of the device, such as geometry,
material composition, grid, contacts,... Furthermore, it sets all parameters
that are needed to define the program flow of nextnano++. The
keywords that can be used for this purpose are defined in the
the input file.
nextnano++ exports its results to a
directory and in a certain format that have to be specified in the section
output of the
The nextnano++ installation provides
some example input files (
Files (x86)\nextnano\2015_08_19\nextnano++ sample files) that can be run with
nextnanomat, to get familiar with the program.
All material properties that are needed for
simulation are specified as material parameters in database files, which are
provided with the nextnano++ installation. The
database covers a large
amount of zinc blende
(all III-V and diamond-type
like Si, Ge, ...), wurtzite
(GaN, AlN, InN, ...) materials, and their alloys.
