Abstract
Scanning-tunneling-microscope images of layer structure dichalcogenides exhibiting charge-density-waves (CDW’s) have been studied at 4.2 K. CDW amplitudes in the 2H, 1T, and 4Hb phases of have been measured with the strongest CDW phase showing only the superlattice modulation while the weaker CDW phases show simultaneous CDW and surface-atom modulations. In 2H- a well-resolved hexagonal CDW superlattice superimposed on the dominant surface-atom pattern is observed.
