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. ....

For the first time in the world, researchers at the Okinawa Institute of Science and Technology’s Graduate University (OIST) have copied an image showing the internal orbits or spatial distribution of particles in an exitone – a goal that scientists have avoided for over a century.
Excitons are the exciting states of matter found in semiconductors – the keys to many modern technological devices, including solar cells, LEDs, lasers, and smartphones. ....
