二维激子的自旋相关相干输运

Spin-dependent coherent transport of two-dimensional excitons

M. V. Durnev, M. M. Glazov

摘要:

我们提出了一个理论的干涉贡献的二维激子扩散系数。该理论考虑了重空穴激子的四种自旋态。单粒子、电子和空穴、自旋分裂与电子-空穴交换相互作用的相互作用导致激子的局域化或反局域化行为,这取决于系统参数。可能的激子干涉的实验表现进行了讨论。

英文摘要:

We propose a theory of interference contributions to the two-dimensional exciton diffusion coefficient. The theory takes into account four spin states of the heavy-hole exciton. An interplay of the single particle, electron and hole, spin splittings with the electron-hole exchange interaction gives rise to either localization or antilocalization behavior of excitons depending on the system parameters. Possible experimental manifestations of exciton interference are discussed.
