From: A study of size-dependent properties of MoS2 monolayer nanoflakes using density-functional theory
Nanoflakes of MoS2 monolayer having 105 atoms before geometry optimization: (a) zigzag edge configuration; (b) armchair edge configuration. Large, green atoms are Mo and small, yellow are S. Corner labels are defined as: a(Mo) = acute-Mo; a(S) = acute-S; o(Mo & S) = obtuse-Mo and S.
