(a) Calculated X-ray elastic strains in a quasi-isotropic Cu thin film with equibiaxial stress of 100 MPa. (b) X-ray elastic constants { s1 } hkl and { s2/2 } hkl refined from (a), plotted as a function of 3Γhkl. (c) Reciprocal diffraction Young's moduli 1/{ E} hkl obtained from (b). The mechanical modulus can be extrapolated for 3 = 0.6, resulting in a value of 123.45 GPa. |
