Owing to prospective energy-efficient and environmentally benign applications, organic
ferroelectric materials are useful and necessary alternatives to inorganic ferroelectrics …

While nature provides a plethora of perovskite materials, only a few exhibit large
ferroelectricity and possibly multiferroicity. The majority of perovskite materials have the …

X-ray absorption spectroscopy (XAS) is a powerful experimental tool to probe the local
structure in materials with the core hole excitations. Here, the oxygen K-edge XAS spectra of …

Persistent photoresponses require optical excitations to metastable states, which are rare of
ionic origin due to the indirect photon-ion interaction. In this work, we explore the …
