摘要：
Spin dynamics in the self-assembled InP quantum dots is studied experimentally. The spin coherence relaxation is analyzed by studying two types of quantum beats observed in photoluminescence kinetics in an external magnetic field. It is found that the spin coherency in the quantum dots rapidly decays due to the reversible phase relaxation related to a spread of the exchange and Zeeman splittings of the electron-hole levels.
