Evaluation of the physical properties and the real space observation in 2H-TaS2 synthesized with flux method

Abstract

Abstract Single crystal of 2H-TaS2 was synthesized with flux method using the flux in which alkali metal ions were included. Analysis of the composition and the structure by EDX measurements and X-Ray diffraction showed that the hydrates of potassium ion were intercalated in 2H-TaS2 synthesized with NaCl/KCl flux. The local intercalation was confirmed by the observation of the superstructures with the period of 2a0 × 2a0 or √3a0 × √3a0 by scanning tunnelling microscopy measurements.
