Abstract

We report on a scanning tunnelling microscopy study of TaS₂ at 4.2 K. A surface prepared by cleavage showed a superimposed pattern of two types of charge density waves with 3a ₀ × 3a ₀ and periodicity, which had never been observed previously. We attribute the superposition to regular stacking of 4H _b polytypes or irregular stacking of 2H and 4H _b layers.
