2H-TaS2晶体呈六边形,具有金属外观。 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)...
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 ...

层状2H-TX2 (T=Nb、Ta和X=S、Se)对电荷密度波(CDW)和超导表现出丰富的维数效应;但在2H-TX的二维极限下,对于这些关联量子相的全面认识仍不充分,阻碍了它们的实际应用。在此研究中,作者根据第一性原理计算了NbSe2、TaS2、TaSe2和NbS2单层中声子线宽和磁化率,研究了CDW形成的起源,分析了它们的相对CDW强度,并...
We report on the observation of the 181Ta nuclear quadrupole interaction in 2H TaS 2 in the temperature range from 5.5 K up to 453 K studied by time differential perturbed angular correlations. Our results for the charge density wave (CDW) state are at variance with all triple-ov|haruq ...
Here, we experimentally demonstrate localized plasmons in a correlated 2D charge-density-wave (CDW) material: 2H-TaSe2. The plasmon resonance can cover a broad spectral range from the terahertz (40 μm) to the telecom (1.55 μm) region, which is further tunable by changing thickness and...
