High-Mobility CdSe Thin-Film Transistors and Circuits by Sol-gel Method

We exploit large-area and high-performance solution-processed CdSe thin-film transistors (TFTs) and 7-stage ring oscillators. A CdSe thin-film was successfully demonstrated using relative low temperature (<400 ഒ) sol-gel processing via organoselenide and cadmium precursors. A CdSe thin-film from commercial organic solvent process was used for active layer of thin-film transistors and integrated circuits which demonstrate electron saturation mobilities exceeding 152 cm²/V-s and frequency of 1 MHz in 7-stage ring oscillators on borosilicate glass substrates.
