Excitonic Materials

One hundred years after their discovery, excitons act as the backbone of a large class of low-dimensional and quantum materials showing a truly exotic set of physical, chemical as well as biophysical properties. Current studies of these excitonic materials are progressing rapidly in newer directions, including those in novel materials and next-generation technologies. Therefore, the main focus of this MRS Bulletin theme is to catch recent progresses in the physics of excitons and excitonic materials, encompassing both fundamental understandings of the nature of these quasiparticles and their emerging device applications in various fields.
