A quantitative study of spin-flip co-tunneling transport in a quantum dot
Tai-Min Liu, Anh T. Ngo, Bryan Hemingway +4
We report detailed transport measurements in a quantum dot in a spin-flip co-tunneling regime, and a quantitative comparison of the data to microscopic theory. The quantum dot is f…
Magnetic-Field-Induced Crossover to a Nonuniversal Regime in a Kondo Dot
Tai-Min Liu, Bryan Hemingway, Steven Herbert +2
We have measured the magnetic splitting, , of a Kondo peak in the differential conductance of a Single-Electron Transistor while tuning the Kondo temperature, , along two…
Magnetic Splitting of the Zero Bias Peak in a Quantum Point Contact with a Variable Aspect Ratio
Tai-Min Liu, Bryan Hemingway, Andrei Kogan +2
We report a zero-bias peak in the differential conductance of a Quantum Point Contact (QPC), which splits in an external magnetic field. The peak is observed over a range of device…
Spin polarization control by electric stirring: proposal for a spintronic device
Yu. V. Pershin, N. A. Sinitsyn, A. Kogan +2
We propose a spintronic device to generate spin polarization in a mesoscopic region by purely electric means. We show that the spin Hall effect in combination with the stirring eff…
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…
