(1) The document reports on characterization of low-dimensional tantalum trisulfide (TaS3) using scanning tunneling microscopy. (2) Step heights of 12 Angstroms and row spacings of 15.5 Angstroms were measured, consistent with previous reports of the material's crystal structure. (3) Modulation along the crystal chains was also observed to match expectations, and spectroscopy data confirmed the metallic nature of flakes larger than 10 nm.
