ThoFeOne is a Python module for the caclulation of the one-dimensional self- consistent quantum-Poisson problem in the Thomas-Fermi approximation. It also includes analytical equations for coparing the simultor results. It can be used to calculate the electronic densities in two-dimensional electron gases at heterostructures of GaAs-based devices.

This includes AlGaAs/GaAs of different alloy concentrations, or other materials used for 2DEGs in heterostructures and different doping densities.

The calculation of the density of states is done using the effective mass appro- ximation.Only the effective mass and relative dielectric constants are required for the solution of the problem. The doping density is also given as parameter, as well as the voltage at the gate (top and/or bottom).

The analytical model includes various cases of the same structure (which is also given as an example for the 1D simulator). The cases are with/without the quantum capacitance, with/without the quantum term (Poisson only) etc.

INSTALL

After upgrading setuptools, type in the directory containing the unpacked module:

<python executable> -m pip install -e thofeone

where <python executable> depends on the platform, i.e. "python" for Linux, "py" for Windows. Then add the directory path that contains the module in PYTHONPATH either permanently, or adding in your code:

import os
path = 'module path'
os.environ['PATH'] += ';'+path
