Exploring the origin of polaron formation in halide perovskites

Halide perovskites are a class of materials with an underlying structure resembling that of mineral perovskites, but with X sites occupied by halide ions, while their A and B sites are occupied by cations. These materials have various advantageous properties that make them promising candidates for the development of photovoltaics (PVs), light-emitting diodes (LEDs) and

Researchers tune Casimir force using magnetic fields

Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences have achieved a reversible transition from the Casimir attraction to repulsion under magnetic field control by using a magnetic
