Notes: Quantum transport properties through a variety of electron waveguide structures that have a double-bend geometry are investigated using the recursive Greens function technique. The conductance is calculated as a function of the chemical potential using the two-probe, multichannel Landauer–Büttiker formula. The results for the right-angle double-bend structure are in agreement with previous calculations based on mode-matching techniques. For multiple double-bend structures in series, the existence of an energy gap between the first and second subband threshold energies where the conductance is suppressed is shown. The effects of disorder and thermal broadening on the conductance are also investigated.
