Browsing: Excitons
Excitons are quasiparticles formed when an electron in a semiconductor or insulator absorbs energy and becomes excited, creating a bound state with the positively charged “hole” it leaves behind. This electron-hole pair, bound by electrostatic Coulomb forces, behaves as a single particle and can transport energy without carrying a net electric charge. Excitons play a significant role in the physics of optoelectronic devices, such as solar cells, LEDs, and certain types of lasers. They are also central to understanding light-matter interactions in advanced materials like quantum dots and 2D materials, making them a crucial concept in condensed matter physics and nanotechnology.
