Abstract: The structure-function motifs in optoelectronic materials, like the perovskite-related metal halides, are usually complicated which makes the understanding of structure-property relationships challenging. As a thermodynamic parameter, pressure provides an effective and clean approach to adjust the atomic interactions and thus modulate the structural units without changing chemical compositions. In this talk, I will present our recent efforts in investigating metal halides and beyond using high pressure, focusing on the modulation of their structural units and the influence on physical properties. Usingin situsynchrotron-based and in-laboratory diagnostic tools, we investigated the evolution of the lattice, electronic, optical, and optoelectronic properties and elucidate their structure-property relationships.
