This code solves the time independent Schroedinger equation in 3D with a constant mass.
It uses 2 different algorithms that can be switched ON/OFF:
-> The FDM: Finite Difference Method (you have to be gentle with the amount of meshing points)
-> The PWE: Plane Wave Expansion method that solves the equation in the Fourier space

Different potentials are proposed:
-> InAs/GaAs quantum dot (lens)
-> InAs/AlInAs quantum dash
-> GaN/AlN quantum dot (pyramidal with hexagon base with Electrical Field)

Any potential can be loaded with homogeneous grid x,y,z [m] and V [eV]
