Study of composition modulation in Cu/Co(Cu) multilayers electrodeposited using pulse trains

Composition modulation in copper/cobalt (copper) multilayers grown by a pulse train based deposition technique has been studied using grazing angle X-ray diffraction and X-ray photoelectron spectroscopy techniques. Higher pulse frequency employed during pulse electrodeposition, has been shown to yield a mixed copper/cobalt phase. Formation of coherent multilayers exhibiting antiphase oscillation of the Cu/Co composition profile has been demonstrated using pulse frequency (duty cycles) of 200 Hz (50%) and 400 Hz (80%) for copper and cobalt electrodeposition, respectively.
