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 ...
In its 2H-phase, TaS2 is a 2D superconductor with a critical temperature (Tc) of 0.2K, and it exhibits incommensurate charge density waves (CDW) below ~80K. We use the flux zone method to produce defect-free crystals, though we also offer a chemical vapor transport (CVT) option, which...

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...
本文通过APCVD和LPCVD两种合成策略,在金箔上实现了TaS2大面积薄膜和厚度可控单晶之间的完美切换,同时还发现了其清晰可辨的CDW转变,以及与铂相当的催化析氢性能。基础性质研究与应用探索相结合使得金属型TMDs的优异潜能跃然纸上。此工作成功发表在Nature Communciations上!

We systematically investigated the influence of defects on charge–density–wave (CDW) and superconductivity (SC) in 1T and 2H-TaS2. The defects can induce SC to 1T-TaS2 system, and inhibit the commensurate CDW (CCDW) and Mott insulator phase, the superconducting transition temperature (TcOn...
