We propose three methods to enhance switching characteristics of p-type Cu₂O thin film transistors (TFTs) by passivating the copper oxide TFTs with silicon dioxide (SiO₂) using sputtering, oxidizing the back channel of copper oxide with hypochlorous acid (HClO), and doping gallium into the Cu₂O film.
