Graphene Phenomenon Could Enable New Lasers
DRESDEN, Germany, Nov. 25, 2014 — Understanding the dynamics of electrons in graphene under strong magnetic fields could lead to development of new types of broadband lasers. An international team led by Helmholtz-Zentrum Dresden-Rossendorf (HZDR) exposed graphene to a 4-Tesla magnetic field, which forced electrons in the material into certain energy states called Landau levels. These energy levels were then examined with a free-electron laser. Electron redistribution through Auger scattering has...
