WebWO3 has a basic octahedron structure. From -140 ∼ 830°C, the crystal structure changes from monoclinic to triclinic, again monoclicnic, then successively orthorhombic, tetragonal, and again tetragonal. Several groups have investigated the electronic structure of WO3 within DFT, but the band gap is severely underestimated compared with ...

The crystal structure of tungsten trioxide is temperature dependent. It is tetragonal at temperatures above 740 °C, orthorhombic from 330 to 740 °C, monoclinic from 17 to 330 °C, triclinic from -50 to 17 °C, and monoclinic again at temperatures below -50 °C. The most common structure of WO3 is monoclinic with space group P21/n. The pure compound is an electric insulator, but oxygen-deficient varieties, such as WO2.90 = W… WebDec 20, 2024 · High ionic conductivity in low-cost semiconductor oxides is essential to …
