Influence of defects on charge-density-wave and superconductivity in 1T-TaS2 and 2H-TaS2 systems

) is about 0.7 K. For 2H-TaS2, the defects nearly have no effect on CDW, while TcOnset is increased to about 2.7 K. The magnetization hysteresis loops show typical type-II superconductor behaviors for both 1T and 2H-TaS2 systems.
