Supercell band folding

WebThe contribution from supercell itself to the. > dielectric peak seems not to make sense physically. For if band-folding can affect the value of dielectric function, then even for pure FCC Au we may get significantly. > different dielectric functions by choosing "unit cell" of different size (say 1x1x1, 4x4x4 times primary cell ) >. WebThe purpose of the band unfolding scheme is to represent the bands within the primitive cell BZ. By calculating the unfolding weight function and plotting the fat bands with the line width proportional to the weight, the unfolded bands can be highlighted. Note: The Brillouin zone of a supercell shrinks respect to the primitive cell.

Webfolding [17–19]. Zone folding occurs because of a shrinking of the BZ of supercells. Larger real-space dimensions lead to a smaller reciprocal space causing information to be ‘folded’ in from lower order BZs [19].
