Abstract
[(SnSe)1+δ]m(NbSe2) (m = 1–6, 8, and 12) highly orientated crystals 1–2 mm in size and well-defined c-planes were successfully grown using CsCl/KCl flux, including the first growth of crystals with m = 12. The stacked layers along the c axis in the obtained crystals were directly observed by transmission electron microscopy as m alternating layers of SnSe and single layers of NbSe2. The superconducting transition temperature of the obtained [(SnSe)1+δ]m(NbSe2) crystals decreased with an increase in the number of SnSe layers per unit cell. As the superconducting anisotropy parameters increase, a significant increase is observed between m = 4 and 5. This indicates that the superconducting dimensionality becomes more two-dimensional with an increasing m.
