Detailed Description

Structure described by the class

two_terminal_structure.jpg

The drawing represents a two-terminal structure made of two leads, of a scattering region and of two interface regions between the leads and scattering center. However, additional lead can be added to the structure. Each rectangle describes a unit cell including singular and non-singular sites. The scattering center is, on the other hand, represented by a larger rectangle corresponding to the Hamiltonian of the scattering region. Arrows indicate the hopping direction stored by the attributes in the corresponding classes (see attributes CreateLeadHamiltonians.H1 and InterfaceRegion.Hcoupling for details). The orientation of the lead is +1 if the lead is terminated by the interface region in the positive direction, and -1 if the lead is terminated by the interface region in the negative direction. (see attribute CreateLeadHamiltonians.Lead_Orientation for details)
