| + | A broadening energy can be defined by the command ''<Broadening>''. Indeed, scattering is not accounted in the contact, so that this commands allows a phenomenological broadening of the density of states in the contact. | ||
| + | |||
| + | The command ''<Ballistic>'' can be used to calculate ballistic transport between the contacts (i.e. no scattering process considered) if its value is set to ''yes''. | ||
