To study low dimensional quantum materials and their quantum effects an international team of researchers (USA – Rensselaer Polytechnic Institute, Florida State University, UC Berkeley, Japan) built a device by stacking multiple atomically thin materials together, including graphene, boron nitride and tungsten diselenide. They showed that as the density of the exciton increases, more electrons and holes pair together, forming four-particle and even five-particle excitonic complexes. They revealed the true biexciton state, a unique four-particle complex responding to light and the nature of the charged biexciton, a five-particle complex. The research gives rise to fundamental understanding of the light-matter interaction in two dimensions and leads to novel applications…read more. Open Access TECHNICAL ARTICLE
