Kiel nano-scientists take snapshots of electronic states
How fast an intense laser pulse can change the electrical properties of solids is revealed by researchers from Kiel University in the current edition of Nature (09.03.2011). Scientists in the team of Professor Michael Bauer, Dr. Kai RoÃÅ¸nagel and Professor Lutz Kipp from the Institute of Experimental and Applied Physics, together with colleagues from the University of Kaiserslautern and the University of Colorado in Boulder, U.S.A., are following the course of electronic switching processes which occur within fractions of a second (femtoseconds). The results of their research may trigger future developments of custom-made and ultra fast opto-electronic components in order to increase data transmission rates or to accelerate optical switches, to name just one example of potential areas of application.
