Transistors: Chemically Functionalized, Well‐Dispersed Carbon Nanotubes in Lithium‐Doped Zinc Oxide for Low‐Cost, High‐Performance Thin‐Film Transistors (Small 14/2016)

A simple, wet-chemical method for the surface functionalization of carbon nanotubes with hydrophilic groups is introduced in Li-doped ZnO by S. Jeong, M. H. Ham, and co-workers, on page 1859. This results in the uniform spatial distribution of single-walled carbon nanotubes in ultrathin ZnO-based matrix oxides, and facilitates high-mobility, low-cost metal-oxide-based thin-film transistors. This approach is compatible with various film formation processes, even printing processes, and enables the realization of high-performance, cost-effective, large-area electronics and displays based on metal oxides.
