University of Central Florida researchers have developed a new and better way of detecting interactions between light and matter at the atomic level, a discovery that could lead to advances in the emerging field of two-dimensional materials and new ways of controlling light.

Scientists typically use spectrometry tools to study the way light interacts with a gas, liquid or solid. That method is described as “inelastic,” meaning the light’s is altered by its contact with matter.

A team led by Professor Aristide Dogariu of UCF’s CREOL, The College of Optics & Photonics, has pioneered a way to detecting such interaction on a single layer of atoms – an exceedingly hard task because of the atom’s minute size – using a method that’s “elastic.” That means the light’s energy remains unchanged.
