Explores improved conductivity in transparent IGZO TFTs, suggesting more efficient electronic devices.
Transparent High-Mobility IGZO TFTs Percolation conduction in amorphous IGZO, represented as a rugged landscape, is hindered by localized potential barriers that suppress electron transport. A niobium capping layer is depicted as a tractor that plows through the terrain while scavenging oxygen and generating oxygen vacancies, lowering barriers and smoothing the landscape, accelerating transport and enabling high mobility in fully transparent top-gate IGZO TFTs. See Research Article e00696 by Seung-Beck Lee and co-workers for more details.
