Synthesis and post-heat treatment of complex compositions in Cu-Ti-O system: Phase investigation and optical properties

CuTiO3/TiO2 MSM UV Photodetector with a Type-I Heterojunction for Rapid and Low-Power Detection

“…The Cu–Ti–O system (Cu x TiO y and CuO/TiO 2 compositions) has attracted much attention in the photoelectric field due to its chemical stability, photoelectric property, and nontoxicity. CuTiO 3 prepared by a sol–gel technique might not be a single phase because of the eutectic reaction between CuO and TiO 2 from 500 to 1020 °C. , Given the circumstances, the majority of CuO/TiO 2 PN heterojunctions can form nanoscale barrier capacitances, which contributes to the high dielectric constant of CuTiO 3 . As one of the ABO 3 perovskite oxide materials, CTO has outstanding thermal and chemical stability and a band gap of 2.99 to 3.48 eV, , which covers UV light below 400 nm.…”
