halide
HAL-ide
Definition
A chemical compound consisting of a halogen atom paired with a less electronegative element or radical, specifically used here to refer to lead-halide substances that serve as precursors in perovskite film formation.
Etymology
Derived from the Greek word 'hals' meaning salt, combined with the chemical suffix '-ide' used for binary compounds. It emerged in the 19th century to describe salts of halogen elements like chlorine, fluorine, bromine, and iodine.
In the news
The article describes the conversion of lead-halide precursors into a perovskite phase and notes the redistribution of these compounds during thermal treatment. Understanding this process is key to optimizing the material's crystallization and final device efficiency.
