Electric-Field-Induced Nuclear Spin Resonance Mediated by Oscillating Electron Spin Domains in GaAs-Based Semiconductors
N. Kumada, T. Kamada, S. Miyashita +2
We demonstrate an alternative nuclear spin resonance using radio frequency (RF) electric field (nuclear electric resonance: NER) instead of magnetic field. The NER is based on the…
The Quantum Hall Transition in Real Space: From Localized to Extended States
K. Hashimoto, C. Sohrmann, J. Wiebe +6
Using scanning tunneling spectroscopy in ultra-high vacuum at low temperature (T = 0.3 K) and high magnetic fields (B < 12 T), we directly probe electronic wave functions across an…
Pseudospin Soliton in the Bilayer Quantum Hall State
A. Fukuda, D. Terasawa, M. Morino +6
We investigate a domain structure of pseudospins, a soliton lattice in the bilayer quantum Hall state at total Landau level filling factor , in a tilted magnetic field, where…
Modulation of bilayer quantum Hall states by tilted-field-induced subband-Landau-level coupling
N. Kumada, K. Iwata, K. Tagashira +4
We study effects of tilted magnetic fields on energy levels in a double-quantum-well (DQW) system, focusing on the coupling of subbands and Landau levels (LLs). The subband-LL coup…
NMR Evidence for Spin Canting in a Bilayer nu = 2 Quantum Hall System
N. Kumada, K. Muraki, Y. Hirayama
We investigate the electron spin states in the bilayer quantum Hall system at total Landau level filling factor nu =2 exploiting current-pumped and resistively detected NMR. The me…
Pauli-Spin-Blockade Transport through a Silicon Double Quantum Dot
H. W. Liu, T. Fujisawa, Y. Ono +4
We present measurements of resonant tunneling through discrete energy levels of a silicon double quantum dot formed in a thin silicon-on-insulator layer. In the absence of piezoele…
