6 天之前 · I need a material that: Is relatively simple to analyze, as I am new to XRD and phase transition studies. Has a well-defined phase transition at an accessible temperature. Hasn’t been widely studied using synchrotron XRD. I initially considered GeSe, BaTiO₃, and MnO₂, but these materials have...
