Unveiling the Electronic Structure of Pseudotetragonal WO Thin Films.

WO 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 WO thin films holds promise in stabilizing electronic phases for practical applications.
