An exciton is a bound state of an electron and an electron hole, which are attracted to each other by the Coulomb force. This quasiparticle plays a crucial role in the optical properties of semiconductors and insulators, especially in nanoscale materials like quantum dots. Excitons can influence electronic transitions, energy transfer processes, and the overall functionality of materials in nanoelectronics.
congrats on reading the definition of Exciton. now let's actually learn it.
