Web1 day ago · The PTCDI lattice on MoS 2 is distorted geometrically, which lifts the degeneracy of the two molecules within the crystal’s unit cell. The degeneracy lifting results in a spatial variation of the molecular orbital energy, with an amplitude and periodicity of ∼0.2 eV and ∼2 nm, respectively. WebA crystal lattice unit cell is the tiniest repeating unit. There are numerous types of unit cells. Known as the “unit cell,” this is the smallest repeating unit in the crystal. Over and over, unit translations can reproduce this three-dimensional shape to fill the structure’s empty spaces (while leaving as few gaps as possible).
