Pressure-Induced Polyhedral Reorganization Causes Indirect-to-Direct Band-Gap Transition in Spinel Structure
Author(s): Pengfei Shen, Donghao Xu, Zhiguo Xia, and Mingguang Yao
Spinel oxides (${\mathrm{AB}}_{2}{\mathrm{O}}_{4}$) are promising optoelectronic materials due to their structural stability and tunable electronic properties. However, conventional strategies like doping, element substitution, and thermal treatment have achieved limited success in optimizing their … [Phys. Rev.
