Spin dynamics of positively charged excitons in Cr${}^{+}$-doped quantum dots probed by resonant photoluminescence

V. Tiwari, M. Morita T. Inoue, S. Ando S. Kuroda +2

We study the dynamics of the spin system that consist of a positively charged II-VI semiconductor quantum dot doped with a single Cr${}^{+}$ ion. The resonant photoluminescence (PL) of…
