0.7 Structure and Zero Bias Anomaly in Ballistic Hole Quantum Wires
0.7 Structure and Zero Bias Anomaly in Ballistic Hole Quantum Wires
We study the anomalous conductance plateau around G=0.7(2e2/h) and the zero bias anomaly in ballistic hole quantum wires with respect to in-plane magnetic fields applied parallel B parallel and perpendicular B perpendicular to the quantum wire. As seen in electron quantum wires, the magnetic fields shift the 0.7 structure down …
