(a) Stress (solid lines) and average momentary (\(D^2_\textrm{min}\) dashed lines) as functions of strain during tensile test. The Young’s modulus is calculated from the linear fitting of the first 1% of the curve. The \(D^2_\textrm{min}\) is calculated with \(r_\textrm{cut}=4.6\) Å. (b) Volume change on the dimension orthogonal to the strained dimension as a function of the volume change on the strained dimension in both a-\({\text {Ga}_{2}\text {O}_{3}}\) and a-\({\text {Al}_{2}\text {O}_{3}}\). The Poisson’s ratio of a-\({\text {Ga}_{2}\text {O}_{3}}\) is fitted from the first 1% strain (\(\Delta z/z <0.01\)) data of a-\({\text {Ga}_{2}\text {O}_{3}}\).
