摘要:

在Ni_(0:05)TaS_2单晶中发现了超导电性。采用NaCl/KCl助熔剂法成功地生长了Ni 0:05 TaS 2单晶。得到的Ni 0:05 TaS 2的晶格常数c为1.1999nm,明显小于2 H-TaS 2的晶格常数c(1.208nm)。电阻率和磁化强度的测量表明,Ni_(0:05)TaS_2的超导转变温度从0.8K(2 H-TaS_2)提高到3.9K。在Ni_(0:05)TaS_2中,基体化合物2 H-TaS_2的电荷密度波跃迁被抑制。NaCl/KCl助熔剂法生长Ni_(0:05)TaS_2单晶的成功表明,NaCl/KCl助熔剂法是一种可行的层状过渡金属二硫属化合物单晶生长方法。

英文摘要:

Superconductivity was discovered in a Ni0:05TaS2 single crystal. A Ni0:05TaS2 single crystal was successfully grown via the NaCl/KCl flux method. The obtained lattice constant c of Ni0:05TaS2 is 1.1999 nm, which is significantly smaller than that of 2H-TaS2 (1.208 nm). Electrical resistivity and magnetization measurements reveal that the superconductivity transition temperature of Ni0:05TaS2 is enhanced from 0.8 K (2H-TaS2) to 3.9 K. The charge-density-wave transition of the matrix compound 2H-TaS2 is suppressed in Ni0:05TaS2. The success of Ni0:05TaS2 single crystal growth via a NaCl/KCl flux demonstrates that NaCl/KCl flux method will be a feasible method for single crystal growth of the layered transition metal dichalcogenides.
