Thin metallic films of a one-dimensional composition modulation have shown increases in elastic moduli of several hundred percent, the supermodulus effect. The effect has typically been observed in noble-transition metal binary systems with one-dimensional long-range order (artificially created by finely controlled deposition techniques). The increase in the elastic moduli is attributable to a fundamental structural bonding change. Correlation of the pseudopotential calculations with the Cu-Ni system predicts the percentage of modulus enhancement for the degree of compressive strain present in the Cu layers.
