Abstract
Abstract
Single crystals of Cs-intercalated NbS2 (Cs
x
NbS2) were synthesized using a CsCl/KCl self-flux. The size and Cs content of Cs
x
NbS2 single crystals increased upon adding Cd metal into the starting materials. When 10–30 at% of Cd per Nb was provided in the starting materials, plate-like Cs
x
NbS2 (x ∼ 0.3) single crystals with 1–2 mm in size and 10–100 μm in thickness were obtained. The superconducting transition temperature of these Cs
x
NbS2 single crystals was 1.65 K.
