硫化钽是一种过渡金属二硫族化合物,在凝聚态物理学和材料科学领域中颇有研究。其层状结构使其表现出许多物理和电学性质,在某些温度和压力条件下,硫化钽可表现出“CDW”(电荷密度波)和“SDW”(自旋密度波)等现象。 2H-TaS2是一种金属和低于~75-80K的不相称电荷密度波(CDW)系统,是Tc ~1K的超导体。TaS2也存在...
2HTaS2 undergoes a charge density wave (CDW) transition at TCDW75 K, however key questions regarding the onset of CDW order remain under debate. In this study, we explore the CDW transition through a combination of temperature and excitation-dependent Raman spectroscopy, angle resolved ...

The CDW mechanism for 2H-TaS2 and the competition between CDW and superconductivity in the NaxTaS2 system are discussed.doi:10.1103/PhysRevB.76.045103W... WZ Hu,G Li,J Yan,... - 《Physical Review B》 被引量: 63发表: 2007年 Fabrication and superconductivity ofNaxTaS2crystals In this pap...
Superconducting Tc can be increased by a low concentration, less than 1%, of irradiation-induced defects in the layered charge-density-wave (CDW) compounds 2H-NbSe2, 2H-TaS2, and 2H-TaSe2. This is due to the pinning effect of the defects which perturbs the long-range coherence of the...
Our results for the charge density wave (CDW) state are at variance with all triple-ov|haruq CDW models and suggest a highly non harmonic electron density perturbation.doi:10.1016/0025-5408(81)90120-3T. ButzA. HüblerA. LerfW. Biberacher...
