| Research Abstract |
Spin-orbit interaction in semiconductor can be considered as a fundamental principle on which next generation electronics, such as quantum information devices, are based. In this research, we chose the In_<0.53>Ga_<0.47>As/In_<0.52>Al_<0.48>As quantum well system as a standard material for spintronics and revealed the spin-orbit parameters quantitatively by electron transport measurements at low temperatures including spin interference effect.
