The motion of tracer particles in turbulent superfluid He down to the zero-temperature limit
C. O. Goodwin, M. J. Doyle, J. A. Hay +4
An injection system for polymer particles, with diameters ranging from 1 to 6 m, has been developed for visualizing flows in superfluid He at temperatures down to 0.14 K. Us…
Apparatus to visualize flows in superfluid He below 1 K
I. Skachko, J. A. Hay, C. O. Goodwin +4
We describe a versatile apparatus for optical observations of experimental processes at temperatures down to 0.1 K. The cooling is achieved by a wet cryostat with a dilution refrig…
Screening Charged Impurities and Lifting the Orbital Degeneracy in Graphene by Populating Landau Levels
Adina Luican-Mayer, Maxim Kharitonov, Guohong Li +7
We report the observation of an isolated charged impurity in graphene and present direct evidence of the close connection between the screening properties of a 2D electron system a…
Fractional quantum Hall effect and insulating phase of Dirac electrons in graphene
Xu Du, Ivan Skachko, Fabian Duerr +2
In graphene, which is an atomic layer of crystalline carbon, two of the distinguishing properties of the material are the charge carriers two-dimensional and relativistic character…
Integer and Fractional Quantum Hall Effect in Two-Terminal Measurements on Suspended Graphene
I. Skachko, X. Du, F. Duerr +4
We report the observation of the quantized Hall effect in suspended graphene probed with a two-terminal lead geometry. The failure of earlier Hall-bar measurements is discussed and…
Towards ballistic transport in graphene
Xu Du, Ivan Skachko, Eva Y. Andrei
Graphene is a fascinating material for exploring fundamental science questions as well as a potential building block for novel electronic applications. In order to realize the full…
