Figure 6: Local-spring-constant distributions.
From: Observation of higher stiffness in nanopolycrystal diamond than monocrystal diamond
(a) C6-H2 model and (b) C2-H6 model. The S- and L-bond spring constants are normalized by those of cubic diamond (SC=1.056 × 1022 N m−3 and LC=0.684 × 1022 N m−3). The spring constants in hexagonal diamond are also shown with green bars for comparison.
