Scientists have cultured the first stable coral cell lines

Exciting exciton breakthrough

Exciting exciton breakthrough The research team generated an image of the exciton s probability cloud by measuring the wavefunction. Credit: OIST. Scientists have just experimentally measured the wave function of an exciton, and they’re excited about it – because they’ve been waiting a century. An exciton is an excited state of matter, created when an electron gains energy and jumps to a higher energy level. The negatively charged electron leaves behind a positively charged empty space (a “hole”), and the two are attracted to each other and begin to orbit each other – together forming an exciton. These electrically neutral “quasiparticles” are crucially important to semiconductors, which are key to applications such as solar cells, lasers and LEDs.

Scientists capture first ever image of an electron s orbit within an exciton

Okinawa Institute of Science and Technology Graduate University Highlights Excitons are excited particles that form when negatively charged electrons bind to positively charged holes Researchers have now used cutting-edge technology to capture the first ever image of the electron inside of an exciton The technique uses extreme ultraviolet light to break excitons apart and kick the electrons into the vacuum of an electron microscope By measuring the angle at which the electrons are ejected from the material, the research team determined how the electrons and holes orbit each other in an exciton Press Release In a world-first, researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have captured an image showing the internal orbits, or spatial distribution, of particles in an exciton – a goal that had eluded scientists for almost a century.
