Quantum dot behavior in graphene nanoconstrictions
Kathryn Todd, Hung-Tao Chou, Sami Amasha +1
Graphene nanoribbons display an imperfectly understood transport gap. We measure transport through nanoribbon devices of several lengths. In nanoribbons of length greater than or e…
Measurements of the spin relaxation rate at low magnetic fields in a quantum dot
S. Amasha, K. MacLean, Iuliana Radu +4
We measure the relaxation rate of a single electron spin in a quantum dot at magnetic fields from 7 T down to 1.75 T, much lower than previously measured. At…
Kondo-temperature dependence of the Kondo splitting in a single-electron transistor
S. Amasha, I. J. Gelfand, M. A. Kastner +1
A Kondo peak in the differential conductance of a single-electron transistor is measured as a function of both magnetic field and the Kondo temperature. We observe that the Kondo s…
Measurements of Kondo and spin splitting in single-electron transistors
A. Kogan, S. Amasha, D. Goldhaber-Gordon +3
We measure the spin splitting in a magnetic field of localized states in single-electron transistors using a new method, inelastic spin-flip cotunneling. Because it involves on…
