Figure 4.

(a) Young’s modulus in the x-direction, $E_{xx}$, and (b) bimodular factor ${\alpha }^{\mathrm{bi}}$ from all simulations. The domain-size effect is considered by both number of atoms in the domain N and simulation domain volume $V_{\mathrm{d}}$. ${\alpha }_2^{\mathrm{bi}}$ and ${\alpha }_1^{\mathrm{bi}}$ describe the bimodularity of T2 and C2, and of T1 and C1 simulations, respectively. The gray shaded area describes the "safe zone", which is discussed in Section 3.5.
