AQUILA is a MATLAB toolbox for the one- or twodimensional simulation of ％the electronic properties

%Known bugs and things that AQUILA 1.0 cannot handle
%
%- The material database might not be completely correct, I just copied some
%  values from some papers and code and some values from Landolt-Bornstein/Adachi.
%
%- The Gamma nonparabolicity is taken into account only for classical treated
%  electron densities. For quantum densities and for the computation of
%  energy levels the parabolic approximation is used. Thus especially higher 
%  levels and densities in higher subbands may be wrong.
%
%- The algorithm may be failing to converge for certain boundary conditions
%  and structures as the iteration gets trapped in a local minimum.
%
%- p-doping is included only as fixed space charge.
%
%- drift and diffusion is not included. Thus diffusion regions can not be handeled properly.
%
%- Sometimes a 'matrix close to singular' warning from routine 'inviter' occurs.
%  This may be ignored.
%
%- inverse vectoriteration sometimes loses eigenvalues.
%
%- several other simplifying assumptions. Mail me for the details on whether and how
%  something is treated.
