摘要：
Single crystal of Cu0.03TaS2 with low copper intercalated content was successfully grown via the chemical vapor transport method. The structural characterization results show that the copper intercalated 2H-Cu0.03TaS2 single crystal has the same structure of the Cdl(2)-type structure as the parent 2H-TaS2 crystal. Electrical resistivity and magnetization measurements reveal that 2H-Cu0.03TaS2 becomes a superconductor below 4.2 K. Besides, electrical resistivity and Hall effects results show that a charge-density-wave transition occurs at T-CDW=50 K. (C) 2008 Elsevier B.V. All rights reserved.
