Optoelectronics

An international research team has developed a 'self-etching' technique to process soft and unstable ionic crystal lattice semiconductors, specifically 2D perovskite thin-layer single crystals, without damaging their structure, overcoming a key challenge in optoelectronic materials. Led by researchers from the University of Science and Technology of China, Purdue University, and Shanghai Tech University, the study was published on Thursday in Nature.
