Experimental Verification of a Spin-Interference Device Action

Yu Iwasaki, Yoshiaki Hashimoto, Taketomo Nakamura, Shingo Katsumoto

摘要:

本文报道了在量子点位于导电路径上的Aharonov-Bohm型干涉仪中探测自旋干涉信号。我们发现像量子点这样的共振器可以作为有效的自旋旋转器工作。只有当自旋极化电子注入器件时,干涉信号才会出现。在栅电压-磁场平面上的干涉图样是棋盘状的,保证了自旋波函数相位和轨道相位的调制。

英文摘要:

We report the detection of spin interference signal in an Aharonov-Bohm type interferometer with quantum dots on the conduction paths. We have found that resonators like quantum dots can work as efficient spin rotators. The interference signal appears only when spin-polarized electrons are injected into the device. The interference pattern in the gate voltage-magnetic field plane is checker board like, ensuring the modulation of spin wavefunction's phase as well as the orbital phase.
