The article conveys some information:
This work reports development of yttrium doped copper oxide (Y-CuO) as a new hole transport material with supplemented optoelectronic character. The pure and Y-doped CuO thin films are developed through a solid-state method at 200°C and recognized as high performance p-channel inorganic thin film transistors (TFTs). CuO is formed by oxidative decomposition of copper acetylacetonate, yielding 100 nm thick and conductive (40.9 S cm-1) compact films with a band gap of 2.47 eV and charge carrier d. of ∼1.44×1019 cm-3. Yttrium doping generates denser films, Cu2Y2O5 phase in the lattice, with a wide band gap of 2.63 eV. The elec. conductivity increases 9-fold on 2% Y addition to CuO, and the carrier d. increases to 2.97×1021 cm-3, the highest reported so far. The TFT devices perform remarkably with high field-effect mobility (μsat) of 3.45 cm2 V-1 s-1 and 5.3 cm2 V-1 s-1, and considerably high current-on/off ratios of 0.11×104 and 9.21×104, for CuO and Y-CuO films, resp. (at -1 V operating voltage). A very small width hysteresis, 0.01 V for CuO and 1.92 V for 1% Y-CuO, depict good bias stability. Both the devices work in enhancement mode with stable output characteristics for multiple forward sweeps (5 to -60 V) at -1Vg. In the experiment, the researchers used many compounds, for example, Bis(acetylacetone)copper(cas: 13395-16-9Recommanded Product: Bis(acetylacetone)copper)
