    Description: The transition-metal dichalcogenides provided a good platform for the investigation of superconductivity and charge-density-wave (CDW) order. A series of high quality 6 R -TaS 2− x Se x (0 ≤  x  ≤ 1.6) single crystals were fabricated by the chemical-vapor-transport method and systematically investigated. The CDW becomes more stable with more S being replaced by Se, which causes expansion of the lattice, and produces a negative chemical pressure in the system. The x dependence of the onset of superconductivity ( T c onset ) shows a dome-like shape with a maximum of T c onset  = 2.7 K at x  = 0.8. The magnetic susceptibility (4π χ ) of x  = 0.8 under the hydrostatic pressure P  = 1.0 GPa was also measured, which showed a small increase of T c and superconducting volume fraction. A pronounced peak effect was observed in the isothermal hysteresis with magnetic field ( H ) parallel to c -axis, which may arise from the quenching inhomogeneity and/or the stacking disorder. Finally, the evolution of the electronic states tuned by Se-doping was summarized in the phase diagram.
