## Description

- description: We investigate the bulk photovoltaic effect in monolayer SnS using
    an effective tight-binding model derived from first-principles calculations. By
    comparing short-range and long-range hopping models, we show that the essential
    features of the shift current conductivity are captured by a minimal model. The
    shift current is decomposed into transition intensity and shift vector, enabling
    identification of dominant interband transitions. The comparison reveals that
    long-range hopping processes quantitatively modify the peak positions and magnitudes,
    while the short-range model retains the characteristic low-energy structure of
    the nonlinear response. Our findings provide a transparent framework for understanding
    and designing bulk photovoltaic effects in two-dimensional materials.
