Functions

'bandstructure': Find the eigenstates of the Hamiltonian with closed BC (mainly for quantum well)

'transport', 'WF': Solve the SE with open BC. Determine the transmission and the DOS.

'transport', 'NEGF': Find the Green's function to the SE with open BC. Determine the transmission and the DOS.

'self_consistent': Do 'transport' and determine the density. Update the electrostatic potential and repeat. Determine the current.

'scattering': NEGF with scattering in a self-consistent loop. No Poisson. Determine the density and the current.
