consisting of Al-doped ZnO (AZO) and ultrathin Au layers, sputtered on polyethylene
terephthalate (PET). These electrodes are relevant for optoelectronic devices and thin film
photovoltaics. When deposited on AZO, Au films as thin as 3 nm form electrically conductive,
meandering structures, whereas uniform Au films are obtained from a thickness of 5 nm. The
sheet resistance decreases with Au thickness, reaching 7 Ω for 11 nm-thick Au. AZO/Au/AZO …
