Electrodeposition of silver from a KAg͑CN) 2 -KCN electrolyte was investigated. The addition of potassium selenocyanate ͑KSeCN͒ results in a hysteretic current-voltage response, specular films, and superconformal growth in submicrometer vias. These observations are well described by the recently proposed curvature enhanced accelerator coverage model of film growth.
