Abstract
This disclosure provides p-type metal oxide semiconductor materials that display good thin film transistor (TFT) characteristics. Also provided are TFTs including channels that include p-type oxide semiconductors, and methods of fabrication. The p-type metal oxide films may be hydrogenated such that they have a hydrogen content of at least 10atoms/cm, and in some implementations, at least 10atoms/cm, or higher. Examples of hydrogenated p-type metal oxide films include hydrogenated tin (II)-based films and hydrogenated copper (I)-based films. The TFTs may be characterized by having one or more TFT characteristics such as high mobility, low subthreshold swing (s-value), and high on/off current ratio.
