Résumé | We report on the observation and study of quantum transport diamonds and Zero Current Anomaly (ZCA) in the non-linear differential resistance r xx=dV xx/dI of high-mobility In xGa 1-xAs/InP structures in quantizing magnetic fields. The diamond-shaped features are observed in the grey-scale plots of r xx as a function of magnetic field and dc current. Spin diamonds are revealed at higher magnetic fields when spin levels at odd filling factors are well resolved. Unexpectedly, a narrow dip is observed in differential resistance vs. current at I dc=0 in quantizing magnetic fields, which we refer to as the ZCA effect. © 2011 American Institute of Physics. |
