Role of Alkaline-Earth Metal in Solution-Processed Indium Oxide Based Thin-Film Transistors
Year: 2012
Type: article
Abstract: We fabricated alkaline-earth metal doped indium oxide thin-film transistors (TFTs) using a solution process. To analyze the effects of Mg, Ca, and Sr on the solution-processed indium oxide TFTs, thermogravimetric analysis, X-ray diffraction, atomic force microscopy analysis, and X-ray photoelectron spectroscopy were performed. The main difference in electrical performance results from the dehydroxylation energy of alkaline-earth metal, each ion radius and optical band gap. The optimized Mg-, Ca-, and Sr-doped indium oxide TFTs show mobilities of 2.03, 1.64, and 1.08 cm 2 V -1 s -1 , respectively, and an on-off current ratio of about ∼10 5 .
