    "description": "We investigate the superconducting properties of molybdenum disulphide (MoS\u2082) monolayer across a broad doping range, successfully recreating the so far unresolved superconducting dome. Our first-principles findings reveal several dynamically stable phases across the doping-dependent phase diagram. We observe a doping-induced increase in the superconducting transition temperature Tc, followed by a reduction in Tc due to the formation of charge density waves (CDWs), polaronic distortions, and structural transition from the H to the 1T\u2032 phase. Our work reconciles various experimental observations of CDWs in MoS\u2082 with its doping-dependent superconducting dome structure, which occurs due to the 1\u00d71 H to 2\u00d72 CDW phase transition.",
