We have investigated the sub-cycle correlated electron dynamics of nonsequential double-ionization (NSDI) of Ar atom by few-cycle counter-rotating two-color circularly polarized (TCCP) laser fields using a three-dimensional classical ensemble model. Numerical results indicate that NSDI probability sensitively depends on the relative phase of the two components and achieves its maximum at the relative phase 0.7[Formula: see text]. Back analysis of NSDI trajectories shows that the return angle of the electron is closely related to the relative phase of the two components and can continuously be controlled by changing the relative phase. Furthermore, the relative phase also influences the relative contribution of recollision-induced direct ionization (RII) and recollision-induced excitation with subsequent field ionization (RESI) to NSDI and the final emitted direction of the electrons.
