The aim of this project is to investigate and engineer spin-orbit interaction in nanostructured III-V semiconductor heterostructures: Using micromechanical cantilevers we will measure spin and orbital magnetization of two-dimensional electron systems, quantum wires and quantum dots exhibiting zero-field spin splitting of different strength. The de Haas-van Alphen effect at low temperature directly reflects the ground state energy and allows us to quantitatively compare to band structure calculations on spin-orbit interaction and g factors

该项目的目的是研究和设计纳米结构III-V族半导体异质结构中的自旋-轨道相互作用：使用微机械杠杆，我们将测量二维电子系统，量子线和量子点的自旋和轨道磁化，这些系统表现出不同强度的零场自旋分裂。低温下的de Haas-van Alphen效应直接反映了基态能量，使我们能够定量地比较自旋轨道相互作用和g因子的能带结构计算
