  The Semiempirical Pseudopotential Method (SEPM) has emerged as a valuable
tool for accurately determining band structures, especially in the realm of
low-dimensional materials. SEPM operates by utilizing atomic pseudopotentials,
which are derived from DFT calculations. SEPM calculations offer a unique
advantage compared to DFT as they eliminate the requirement for iterative
self-consistent solutions in solving the Schr\"odinger equation, leading to a
substantial reduction in computational complexity. The incorporation of both
non-local and local Semiempirical Pseudopotentials in our current approach
yields band structures and wavefunctions with enhanced precision compared to
traditional empirical methods. When applied to monolayer TMDCs, adjusting the
parameters to align with pertinent values obtained from DFT computations
enables us to faithfully replicate the band structure, opening avenues for
investigating the optoelectronic properties of TMDCs and exploring their
potential applications in nanodevices.
