So far, the influence of this interaction on the very fast electron motions following the absorption of light has remained unclear. (sciencedaily.com)
The next challenges are the observation of faster electron oscillation in the chromium doped sapphire (Cr: Al2O3) insulator and the characterization of the ultrafast electron dephasing. (sciencedaily.com)
The second paper, published May 12, explores fast electrons in a material made from the elements bismuth and selenium. (sciencedaily.com)
