Webexciton, the combination of an electron and a positive hole (an empty electron state in a valence band), which is free to move through a nonmetallic crystal as a unit. Because the electron and the positive hole have equal but opposite electrical charges, the exciton as a whole has no net electrical charge (though it transports energy). WebJun 17, 2024 · His research interests span from fundamental understanding of charge, photon and exciton behaviors to developing next-generation intelligent materials, devices and systems. 1 Introduction Chirality is defined as two enantiomers that are mirror images of each other and cannot overlap.
