Spin dynamics in semiconductors

半导体中的自旋噪声谱已经成为一种强大的工具，可以在不干扰干扰的情况下解开半导体纳米结构中的本征自旋动力学。在这个项目中，该技术的适用性已经从毫秒级发展到亚纳秒级的自旋动力学，从三维半导体发展到低维异质结构。在这个即将到来的项目中，我们将利用自旋噪声光谱的弱干扰特性来探索相互作用的自旋系统的复杂动力学。首先，我们将研究单个或耦合自组装量子点中一个或几个受限电荷的自旋动力学，以及它们与核自旋池的相互作用。其次，我们将研究相关二维电子和空穴气体在超低温下的自旋相互作用。第三，我们将用全光自旋噪声谱研究砷化镓锰中磁性杂质在铁磁-顺磁相变过程中的复杂相互作用。

Spin noise spectroscopy in semiconductors has emerged into a powerful tool to unravel the intrinsic spin dynamics in semiconductor nanostructures without disturbing inuences. The technique's applicability has advanced during this project from millisecond to sub-nanosecond spin dynamics and from three dimensional semiconductors to low dimensional heterostructures. In this upcoming project, we will employ the weakly disturbing features of spin noise spectroscopy to explore the complex dynamics of interacting spin systems. Firstly, we will study the spin dynamics of one or few confined charges in single or coupled self assembled quantum dots together with their interaction with the nuclear spin bath. Secondly, we will investigated the spin interaction of correlated two dimensional electron and hole gases at ultra low temperatures. Thirdly, we will explore the intricate interaction of magnetic impurities at the ferromagnetic to paramagnetic phase transition in gallium manganese arsenide by all optical spin noise spectroscopy.
