In the first scenario, homogeneous irradiation using 20 keV Ar$^+$ ions at a dose of $3 \\times 10^{14}$ ions/cm$^2$ induces tensile strain of up to 0.8\\%. This strain diminishes with increasing defect density at the dose of $5 \\times 10^{14}$ ions/cm$^2$, indicating a strain-relaxation mechanism. Contrary to the expected localized behavior, vacancies exhibit long-range interactions, contributing to global strain effects across the lattice.
