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…
Substrate-Independent Catalyst-Free Synthesis of High-Purity Bi2Se3 Nanostructures
Jerome T. Mlack, Atikur Rahman, Gary L. Johns +2
We describe a catalyst-free vapor-solid synthesis of bismuth selenide (Bi2Se3) nanostructures at ambient pressure with hydrogen as a carrier gas. The nanostructures were synthesize…
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…
