Surface‐functionalized carbon nanotubes (CNTs) are introduced into lithium‐doped ZnO thin‐film transistors (TFTs) as an alternative to the conventional incorporation of an expensive element, indium. The crucial role of surface functionalization of CNTs is clarified with the demonstration of indium‐free ZnO‐based TFTs with a field‐effect mobility of 28.6 cm 2 V −1 s −1 and an on/off current ratio of 9 × 10 6 for low‐cost, high‐performance electronics.
