Unveiling the Electronic Structure of Pseudotetragonal WO₃ Thin Films.

ABSTRACT: WO₃ is a 5d compound that undergoes several structural transitions in its bulk form. Its versatility is well-documented, with a wide range of applications, such as flexopiezoelectricity, electrochromism, gating-induced phase transitions, and its ability to improve the performance of Li-based batteries. The synthesis of WO₃ thin films holds promise in stabilizing electronic phases for practical applications. However, despite its potential, the electronic structure of this material remains experimentally unexplored. Furthermore, its thermal instability limits its use in certain technological devices. Here, we employ tensile strain to stabilize WO₃ thin films, which we call the pseudotetragonal phase, and investigate its electronic structure using a combinatio
