ELECTROCHEMICAL PRODUCTION OF SINGLE-CRYSTAL CU-NI STRAINED-LAYER SUPERLATTICES ON CU(100)

Single-crystal Cu-Ni superlattices were grown on Cu(100) from an elect rolyte containing 1.5 mol/liter Ni(SO3NH2)(2), 0.5 mol/liter H3BO3, an d 0.009 mol/liter CuSO4. Specimens with modulation wavelength ranging from 2.6 to 70 nm have been produced. The films typically cover an are a of similar to 2.5 cm(2) and are similar to 2.4 to 4.7 mu m thick. Th ese materials should be helpful toward understanding the influence of modulation wavelength and orientation on the physical properties of me tallic superlattices.
