Abstract

OTFTs on indium tin oxide (ITO) coated glass with high-k material HfO2as gate dielectric have been successfully fabricated. The devices show small threshold voltage, and thus are suitable for high-speed and low-power operations. This work also finds that OTFT with chlorine pretreatment of ITO has larger drain current, higher mobility, smaller sub-threshold slope and larger on/off ratio than the without chlorine treated sample. This demonstrates that the surface chlorination treatment on ITO gate electrode is a simple, low cost, low-temperature, and effective way to improve the OTFT performance.
