Ferroelectrics are a class of materials that exhibit so-called spontaneous electric polarization, which is the separation of electric charges that can be reversed when an external electric field is applied to them. The dipole moments (i.e., pairs of equal and opposite charges) in these materials can sometimes be arranged in complex configurations known as topological textures.

The topological structures of some ferroelectric materials can interact with light in interesting and unexpected ways, which could have interesting implications for the development of optical technologies and . The size of ferroelectric polar topologies unveiled and studied to date, however, is not aligned with that of laser light modes, which limited their previous use for the development of optical technologies.

Researchers at Nanjing University recently realized a micrometer-scale center-convergent ferroelectric topology using barium titanate (BaTiO3) membranes that enables the precise spatial control of light fields.

A team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has resolved a critical challenge in pure-red perovskite light-emitting diodes (PeLEDs) by identifying and addressing the root cause of efficiency loss at high brightness.

Published in Nature, their study introduces a novel material design that enables record-breaking device performance, achieving a peak external quantum efficiency (EQE) of 24.2% and a maximum luminance of 24,600 cd m-2 —the brightest pure-red PeLED reported to date.

Pure-red PeLEDs, crucial for vivid displays and lighting, have long faced a trade-off between efficiency and brightness. While 3D mixed-halide perovskites like CsPbI3-x Brx offer excellent charge transport, their efficiency plummets under high current due to unresolved carrier leakage.
