## Description

- description: Layer number-dependent band structures and symmetry are vital for the
    electrical and optical characteristics of 2D transition metal dichalcogenides
    (TMDCs). Harvesting 2D TMDCs with tunable thickness and properties can be achieved
    through top-down etching and bottom-up growth strategies. In this study, a pioneering
    technique that utilizes the migration of in situ generated Na-W-S-O droplets to
    etch out 1D nanotrenches in few-layer WS2 is reported. 1D WS2 nanotrenches are
    successfully fabricated on the optically inert bilayer WS2, showing pronounced
    photoluminescence and second harmonic generation signals. Additionally, the modulation
    of inkjet-printed Na2WO4-Na2SO4 particles to switch between the etching and growth
    modes by manipulating the sulfur supply is demonstrated. This versatile approach
    enables the creation of 1D nanochannels on 2D TMDCs. The research presents exciting
    prospects for the top-down and bottom-up fabrication of 1D-2D mixed-dimensional
    TMDC nanostructures, expanding their use for electronic and optoelectronic applications.
