... voltage "F . Note that in perturbation theory the conductance is not bound by its physical limit: 2e2 =h. The dependence of conductance on magnetic field is shown in Fig. 1(b). The Kondo logarithms in G3 are suppressed, leading to the evolution of the 0:7 plateau towards and below 0:5. In agreement ...

... pattern (corresponding to a 5◦ rotation angle between graphene and hBN) is visible26,27 and the region is seen to be free of adsorbates. A dI /dVs map of the same region (Fig. 2c) reflects changes in the local density of states (LDOS) caused by the spatially varying charge density distribution. Sinc ...

Quantized magnetoresistance in atomic-size
... The entire electrochemical cell was rotated by a step motor in a magnetic field of 1 T produced by an electromagnet. Both the angle and the conductance were synchronically recorded as a function of time. The angular rotation was performed from 0° to 180°, with 0° corresponding to the magnetic field ...
