WebNano-porous iridium and iridium oxide thin films formed by high efficiency electrodeposition Ehab N. El Sawy a and Viola I. Birss *a Author affiliations Abstract The goal of this work has been to fabricate very thin, highly porous Ir films, of use in a wide variety of applications. WebIridium oxide thin-films can be deposited through reactive sputtering whether the target is dc-powered [4] or rf-powered [2] in a plasma environment. Iridium oxide species were pulsed dc-sputtered as reported in this work. Pulsed power as opposed to dc-power prevents the formation of arcs [4]. DC-sputtering of dielectrics causes the
