Large nuclear Overhauser fields detected in vertically-coupled double quantum dots
J. Baugh, Y. Kitamura, K. Ono +1
We report the electrical induction and detection of dynamic nuclear polarization in the spin-blockade regime of double GaAs vertical quantum dots. The largest Overhauser field obse…

Single-dot spectroscopy via elastic single-electron tunneling through a pair of coupled quantum dots
T. Ota, K. Ono, M. Stopa +7
We study the electronic structure of a single self-assembled InAs quantum dot by probing elastic single-electron tunneling through a single pair of weakly coupled dots. In the regi…

Nuclear spin induced oscillatory current in spin-blocked quantum dots
Keiji Ono, Seigo Tarucha
Hyperfine coupling of electron spins to nuclear spins is studied for a GaAs-based double quantum dot in the spin blockade regime where the electron conduction is mostly blocked by…
