After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.<\/p>\n

They were the first to control exciton<\/a> flows at room temperature<\/a>. And now, the team of scientists from EPFL\u2019s Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further. They have found a way to control some of the properties of excitons and change the polarization of the light they generate. This can lead to a new generation of electronic devices with transistors that undergo less energy loss and heat dissipation. The scientists\u2019 discovery forms part of a new field of research called valleytronics and has just been published in Nature Photonics.<\/p>\n

Excitons are created when an electron absorbs light and moves into a higher energy level, or \u201cenergy band\u201d as they are called in solid quantum physics. This excited electron leaves behind an \u201celectron hole\u201d in its previous energy<\/a> band. And because the electron has a negative charge<\/a> and the hole a positive charge, the two are bound together by an electrostatic force called a Coulomb force. It\u2019s this electron-electron hole pair that is referred to as an exciton.<\/p>\n
