Electron Spin Observation and Controlling in Quantum Point Contacts

研究了耦合量子点接触(QPC)中的局域磁矩和自旋态的控制。利用半导体或纳米碳材料在微波或太赫兹波辐射下的低温磁阻和扫描门调制，在半导体或纳米碳材料微细加工制备的QPC样品中，可以实现对自旋相关电子波动力学的直接观测。

Localized Magnetic Moment (LMM) and the controlling of the spin state have been studied in the coupled Quantum Point Contacts (QPCs). The direct observation for the spin related electron-wave dynamics, can be realized in the QPCs sample prepared by micro-fabrication in semiconductors or nano-carbon materials by use of the low-temperature magneto-resistances under the microwave or terahertz wave radiation and the scanning gate modulation.
