## Description

- description: The charge density wave (CDW) state of 2H-NbSe2 features commensurate
    domains separated by domain boundaries accompanied by phase slips known as discommensurations.
    We have unambiguously visualized the structure of CDW domains using a displacement-field
    measurement algorithm on a scanning tunneling microscopy image. Each CDW domain
    is delimited by three vertices and three edges of discommensurations and is designated
    by a triplet of integers whose sum identifies the types of commensurate structure.
    The observed structure is consistent with the alternating triangular tiling pattern
    predicted by a phenomenological Landau theory. The domain shape is affected by
    crystal defects and also by topological defects in the CDW phase factor. Our results
    provide a foundation for a complete understanding of the CDW state and its relation
    to the superconducting state.
