Conductance quantization and zero bias peak in a gated quantum wire
Conductance measurements are reported for an 0.4 mm wide GaAs/AlGaAs quantum wire with 7 cross-channel gates. The device exhibited integral conductance steps, magnetoconductance plateaus in agreement with the multiprobe formula and a conductance feature at 0.65(2e/h). Differential conductance measurements down to 50mK revealed a zero bias conductance peak that vanished with an in-plane field of...
متن کاملZero-bias conductance quantization in a normal / superconducting junction of nano wire
We discuss a strong relationship between Majorana fermions and odd-frequency Cooper pairs which appear at a disordered normal nano wire attached to a topologically nontrivial superconducting one. The zero-bias differential conductance in a normal / superconducting nano wire junctions is quantized at 2e/h irrespective of degree of disorder, length of disordered segment, and random realization of...
متن کاملEnhanced zero-bias Majorana peak in the differential tunneling conductance of disordered multisubband quantum-wire/superconductor junctions.
A recent experiment Mourik et al. [Science 336, 1003 (2012)] on InSb quantum wires provides possible evidence for the realization of a topological superconducting phase and the formation of Majorana bound states. Motivated by this experiment, we consider the signature of Majorana bound states in the differential tunneling conductance of multisubband wires. We show that the weight of the Majoran...
متن کاملZero Bias Conductance Peak Enhancement in Bi2Sr2CaCu2O8/Pb Tunneling Junctions
We found strong zero bias conductance peak enhancement in Bi2Sr2CaCu2O8 by tunneling in the ab-plane direction. Our results are consistent with recent studies on Andreev reflection between a d-wave superconductor and normal metal. We have also observed exotic behaviors of the conductance peak if the counter electrode is a conventional superconductor. If these characteristics are better understo...
متن کاملZero-bias conductance in carbon nanotube quantum dots.
We present numerical renormalization group calculations for the zero-bias conductance of quantum dots made from semiconducting carbon nanotubes. These explain and reproduce the thermal evolution of the conductance for different groups of orbitals, as the dot-lead tunnel coupling is varied and the system evolves from correlated Kondo behavior to more weakly correlated regimes. For integer fillin...
