Dynamics of coupled spins in quantum dots with strong spin-orbit interaction
A. Pfund, I. Shorubalko, K. Ensslin +1
We investigated the time dependence of two-electron spin states in a double quantum dot fabricated in an InAs nanowire. In this system, spin-orbit interaction has substantial influ…
Self-aligned charge read-out for InAs nanowire quantum dots
I. Shorubalko, R. Leturcq, A. Pfund +4
A highly sensitive charge detector is realized for a quantum dot in an InAs nanowire. We have developed a self-aligned etching process to fabricate in a single step a quantum point…
Pauli spin-blockade in an InAs nanowire double quantum dot
A. Pfund, I. Shorubalko, R. Leturcq +1
We measure transport at finite bias through a double quantum dot formed by top-gates in an InAs nanowire. Pauli spin-bockade is confirmed with several electrons in the dot. This is…
Spin state mixing in InAs double quantum dots
A. Pfund, I. Shorubalko, K. Ensslin +1
We quantify the contributions of hyperfine and spin-orbit mediated singlet-triplet mixing in weakly coupled InAs quantum dots by electron transport spectroscopy in the Pauli spin b…
Suppression of spin relaxation in an InAs nanowire double quantum dot
A. Pfund, I. Shorubalko, K. Ensslin +1
We investigate the triplet-singlet relaxation in a double quantum dot defined by top-gates in an InAs nanowire. In the Pauli spin blockade regime, the leakage current can be mainly…
Top-gate defined double quantum dots in InAs nanowires
A. Pfund, I. Shorubalko, R. Leturcq +1
We present low temperature transport measurements on double quantum dots in InAs nanowires grown by metal-organic vapor phase epitaxy. Two dots in series are created by lithographi…
