Quantum Interference Noise Near the Dirac Point in Graphene
Atikur Rahman, Janice Wynn Guikema, Nina Markovic
Effects of disorder on the electronic transport properties of graphene are strongly affected by the Dirac nature of the charge carriers in graphene. This is particularly pronounced…
Asymmetric scattering of Dirac electrons and holes in graphene
Atikur Rahman, Janice Wynn Guikema, Nina Markovic
The relativistic nature of Dirac electrons and holes in graphene profoundly affects the way they interact with impurities. Signatures of the relativistic behavior have been observe…
Transmission of phase information between electrons and holes in graphene
Atikur Rahman, Janice Wynn Guikema, Soo Hyung Lee +1
We have studied quantum interference between electrons and holes in a split-ring gold interferometer with graphene arms, one of which contained a pn junction. The carrier type, the…
Observation of angle-dependent transmission of Dirac electrons in graphene hetero junctions
Atikur Rahman, Janice Wynn Guikema, N. M. Hassan +1
The relativistic nature of charge carriers in graphene is expected to lead to an angle- dependent transmission through a potential barrier, where Klein tunneling involves annihilat…
Two-dimensional vortex behavior in highly underdoped YBa_2Cu_3O_{6+x} observed by scanning Hall probe microscopy
J. W. Guikema, Hendrik Bluhm, D. A. Bonn +3
We report scanning Hall probe microscopy of highly underdoped superconducting YBa_2Cu_3O_{6+x} with T_c ranging from 5 to 15 K which showed distinct flux bundles with less than one…
