Excitons are exciting researchers in Switzerland

Last summer, Scientists from EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES) in Switzerland announced they had developed a method to control exciton flows at room temperature. That in and of itself was a pretty big deal. In the latest development, they have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices and have found ...

Last summer, Scientists from EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES) in Switzerland announced they had developed a method to control exciton flows at room temperature. That in and of itself was a pretty big deal. In the latest development, they have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices and have found a way to control some of the properties and change the polarization of the light they generate. This discovery forms part of a relatively new field of research called valleytronics and has just been published in Nature Photonics. Excitons are
