Enhanced performance of solution-processed amorphous LiYInZnO thin-film transistors.

Solution-processed, amorphous lithium-doped YInZnO (L-YIZO) thin-film transistors (TFTs) are investigated. An appropriate amount of Li doping significantly enhances the field-effect mobility in TFT performance (~15 times greater than that of nondoped YIZO) without controlled annealing under water vapor or O(3)/O(2) environments. The addition of Li into solution-processed YIZO semiconductors leads to improved film quality, which results from enriched metal oxygen bonding and reduced defect sites, such as oxygen vacancies and hydroxyl groups.
