Band-Gap Tunability in Anharmonic Perovskite-Like Semiconductors Driven by Polar Electron–Phonon Coupling

The ability to finely tune optoelectronic properties in semiconductors is crucial for the development of advanced technologies, ranging from photodetectors to photovoltaics. In this work, we propose a novel strategy to achieve such tunability by utilizing electric fields to excite low-energy polar o...
