Abstract

Previously¹ we reported the fabrication, structure, and electrical transport properties of Mo/Ta superlattices. This present paper reports a more quantitative analysis used to explain an observed wavelength-dependent strain perpendicular to the layers in terms of the van der Merwe^2,3 model for epitaxial superlattices. These results are correlated with an anomalous decrease in the c₄₄ elastic stiffness constant of Mo/Ta for 20 Å < ∧ < 50 Å.
