Study of Defects Effect on Electronic Conductance Through Binomially Tailored Quantum Wire
H.S. Ashour and A.I. Assad

Abstract:
This study considers the effect of the defects on the electronic conductance properties in Binomially Tailored Quantum Wires (BTQW), in which each Dirac delta function`s potential strength have been weight on the binomial distribution law. A single free-electron channel is incident on the structure and the scattering of electrons is solely from the geometric nature of the problem. We found that this novel structure has a good defect tolerance within ±5% or more for the following defects: single strength defect, dislocation defect, or both defects. Finally, we found this structure has somehow good tolerance for flipped order of the delta potential and missing Dirac delta potential from the binomial pattern.
