 Repeating the unit cell in real space results in folded band structures, as illustrated in \autoref{fig:figure1}, complicating its interpretation and analysis.
 Band structure unfolding maps the electronic structure from supercell calculations back to the reciprocal lattice of the primitive cell,
 thereby enabling researchers to understand structure-property relationships and compare the effect of various crystal imperfections on an equal footing.
