Single-molecule electronic materials. Conductance of π-conjugated oligomers within quasi-correlated tight-binding model
For computing electric conductance through organic nanowire of conjugated type we make use of the recently proposed quasi-correlated tight-binding (QCTB) method. The appropriate Green's function (GF) matrices are constructed, and simple numerical algorithms are given for them. Moreover, the GF...

For computing electric conductance through organic nanowire of conjugated type we make use of the recently proposed quasi-correlated tight-binding (QCTB) method.
