Isothermal pressure-derived metastable states in 2D hybrid perovskites showing enduring bandgap narrowing [Applied Physical Sciences]

Materials in metastable states, such as amorphous ice and supercooled condensed matter, often exhibit exotic phenomena. To date, achieving metastability is usually accomplished by rapid quenching through a thermodynamic path function, namely, heating−cooling cycles. However, heat can be detrimental to organic-containing materials because it can induce degradation. Alternatively, the application...
