Cross-correlation studies using nano angle-resolved photoelectron spectroscopy (nARPES) coupled with scanning tunneling microscopy and scanning tunneling spectroscopy (STM/STS) measure a band gap renormalization on purposefully induced defects in monolayer tungsten disulfide (WS<sub>2</sub>). Mirror twin boundary (MTB) defects are identified with non-contact atomic force microscopy, which enables structural comparison to local studies performed with nARPES and STM. Both nARPES and STS studies a formation of Tomonaga–Luttinger Liquids within mirror twin boundary (MTB) defects, which are created through the growth of one-dimensional (1D) MTBs from point defects tht are induced into WS<sub>2</sub> with Ar<sup>+</sup> bombardment. Chalcogen defect creation also provides a path to study novel substitutional defects. 1D MTBs are substantially charged at the nanoscale.
