In the study, high-performance p-type Te_xSe_yO thin-film transistors were fabricated by RF magnetron sputtering, enabling superior film quality. Al₂O₃ layer was employed as high-k gate dielectric for low-power operation and passivation. The devices exhibited enhanced mobility, improved on/off current ratio, and significantly better long-term stability compared with conventional p-type Te transistors.
