Retention of high-pressure solution-processable metastable phase to ambience via differential sublattice rigidity for broadband photodetectors.

ABSTRACT: Materials science exploits only properties that are available at ambience. Therefore, although high-pressure changes the physical state of all condensed matter, most of the extraordinary properties discovered vanish after decompression and cannot be utilized. Here, we demonstrate sublattice decoupling in a mixed-anion chalcohalide Rb₆Re₆S₈I₈ upon compression, in which the [Rb₆I₂]⁴⁺ framework is soft and plastic, while the [Re₆S₈I₆]^4- clusters are hard and elastic. This discrepancy in the rigidity allows the applied pressure to selectively amorphize the framework while maintaining the ordered state in the cluster, leading to intriguing photocurrent generation and enhancem
