Metallic behaviour in SOI quantum wells with strong intervalley scattering
V. T. Renard, I. Duchemin, Y. Niida +3
The fundamental properties of valleys are recently attracting growing attention due to electrons in new and topical materials possessing this degree-of-freedom and recent proposals…
Valley polarization assisted spin polarization in two dimensions
V. T. Renard, B. A. Piot, X. Waintal +7
Valleytronics is rapidly emerging as an exciting area of basic and applied research. In two dimensional systems, valley polarisation can dramatically modify physical properties thr…
Decoherence of nuclear spins due to direct dipole-dipole interactions probed by resistively detected nuclear magnetic resonance
T. Ota, G. Yusa, N. Kumada +3
We study decoherence of nuclear spins in a GaAs quantum well structure using resistively detected nuclear magnetic resonance. The transverse decoherence time T2 of 75As nuclei is e…
Valley Polarization in Si(100) at Zero Magnetic Field
K. Takashina, Y. Ono, A. Fujiwara +2
The valley splitting, which lifts the degeneracy of the lowest two valley states in a SiO/(100)Si/SiO quantum well is examined through transport measurements. We demonstrat…
Electrical pump-and-probe study of spin singlet-triplet relaxation in a quantum dot
S. Sasaki, T. Fujisawa, T. Hayashi +1
Spin relaxation from a triplet excited state to a singlet ground state in a semiconductor quantum dot is studied by employing an electrical pump-and-probe method. Spin relaxation o…
Non-equilibrium transport through a vertical quantum dot in the absence of spin-flip energy relaxation
Toshimasa Fujisawa, David Guy Austing, Yasuhiro Tokura +2
We investigate non-equilibrium transport in the absence of spin-flip energy relaxation in a few-electron quantum dot artificial atom. Novel non-equilibrium tunneling processes invo…
