lead_param

Description

Structure lead_param contains the physical parameters describing a given lead.>

lead_param

Fields
epsilon On-site energy in the lead.
vargamma The hopping amplitude in the lead.
SOintrinsic strength of the intrinsic SOI in silicene.
deltaAB The strength of the staggered A-B potential in silicene.
SO_rashba_intrinsic The strength of the intrinsic Rashba SOI in silicene.
vargamma1 The strength of the interlayer hopping in bilayer graphene-like materials.
The first hopping term in the SSH model.
vargamma2 Hopping parameter in the BiTeI Hamiltonian.
vargamma3 The strength of the warping hopping in bilayer graphene-like materials.
The second hopping term in the SSH model.
pair_potential The pair potential for superconducting phases (complex number).
Overlap_in_Lead Logical parameter. Set true to use overlap integrals in the lead, false otherwise.
orientation Set $+1$ if the in-comming states to the scattering center are propagating in the $+x$ or $+y$ direction, and $-1$ otherwise.
M The number of the sites in the cross section of the lead.
End_Type Values are 'A' for zigzag edged ribbon (Armchair end), and 'Z' for ribbon with armchair type edges (Zigzag end) in hexagonal lattice.
Atom Cell array of structure Atom.
vargamma_sc Custom hopping parameter between the leads and the scattering region.
FileName Filename containing the custom Hamiltonians. (see Custom_Hamiltonians for details)
