Powder X-ray diffraction (XRD) of a single crystal 1T-TaS2. X-ray diffraction was performed at room temperature using a D8 Venture Bruker.Stoichiometric analysis of a single crystal 1T-TaS2 by Energy-dispersive X-ray spectroscopy (EDX)....
(XRD). We find that, at low temperatures, the band dispersion and diffraction peaks show 2π/2cand 2cperiodicity, which indicates that the ground state of 1T-TaS2is a band insulator with interlayer dimerization. More intriguingly, at high temperatures, the system undergoes an insulator-to-...
2 For the layered transition metal dichalcogenide 1T-TaS2, we establish through a unique experimental approach and density functional theory, how ultrafast charge transfer in 1T-TaS2 takes on isotropic three-dimensional character or anisotropic two-dimensional character, depending on the commensurability...
当 SnBr2:Na2WO4= 1:6时,获得了 2D Sn0.3W0.7S2纳米片。XRD 进一步对这些产物的组成和结构演变进行深入分析,如图2b 所示。当 W 比例很低时,例如在 Sn0.90W0.10S2中,观察到与原始 1T-SnS2相似的峰,表明少量的 W 不会显著改变...
XRD1T-TaS2 was intercalated at room temperature with Li via butyllithium, with Na via an amalgam, and with Hg (at 423 K). The final products were examined via the 181Ta nuclear quadrupole interaction and by powder X-ray diffraction. They were found almost identical to those obtained with ...
在LMDs中,亚稳态(如T-MoS2,T'-MoS2)和金属(如T-TaS2,T-ReS2)材料由于其较高的固有电导率,以及与2H相LMDs相比在基底平面上存在更多的催化活性位点,是有前途的高效HER催化剂。然而,由于相变过程控制的困难,使得亚稳材料和金属材料的应用受到限制。因此,开发一种可靠的、通用的制备亚稳相晶体的方法是非常必要...
