Simulating Transport in Nanodevices Using the Usuki Method

摘要: To calculate the conductance of mesoscopic structures such as quantum wires and dots at low temperature bias, one typically employs Landauer–Buttiker formalism, which relates mechanical transmission probability to conductance. In this chapter, we discuss a numerically stable method solve problem, Usuki method, is closely related both scattering matrix approach recursive Green’s functions. It has major advantage over latter in that electron density can be obtained far more efficiently. Various applications are presented: transport through open dots, study spin filtering effects wire structures, computing molecules application MOSFETS. The extensions basic required for each case also discussed, most extensive MOSFET where inelastic play crucial role.
