Here, pristine and Pd-intercalated 2 H − Ta S 2 single crystals with ( 00 l ) orientation were grown by the chemical vapor transport technique. The superconductivity (SC) and charge density wave (CDW) were characterized by magnetic and electrical transport measurements. We find that SC and CDW in the pristine 2 H − Ta S 2 condense respectively at transition temperatures T c ∼ 0.8 K and T CDW ∼ 78 K . The CDW order is completely suppressed, and T c is greatly enhanced to 4.5 K in 2 H − P d 0.04 Ta S 2 , which concludes a competing relation ...
