The project will provide basic knowledge on the energy and spin structure of the electronic states and exciton complexes in semiconductor colloidal nanostructures of various shapes (spherical quantum dots, nanoplatelets, core/shell heterostructures) and chemical compositions. We will focus on spin-dependent phenomena and dynamics of interacting spin systems of carriers (electrons and holes), excitons (neutral and charged), magnetic ions, surface spins of dangling bonds and nuclei spins. The main task for the project is to perform a comprehensive experimental and theoretical study of spin-dependent phenomena being controlled and modified by strong quantum confinement of carriers and their interaction with the surface.

该项目将提供关于各种形状的半导体胶体纳米结构(球形量子点、纳米片、核/壳异质结构)和化学成分中电子态和激子复合体的能量和自旋结构的基本知识。我们将集中于载流子(电子和空穴)、激子(中性和带电的)、磁性离子、悬挂键的表面自旋和原子核自旋相互作用的自旋系统的自旋依赖现象和动力学。该项目的主要任务是对自旋相关现象进行全面的实验和理论研究，这些现象受到载流子的强量子限制及其与表面的相互作用的控制和修正。
