Vladislav S. Yakovlev on attoworld´s new "Nature" paper explaining photoinjection of charge carriers.
Since the early days of quantum mechanics, scientists have been exploring what exactly happens during photoionization and photoinjection, when an electron gains enough energy from a light wave to free itself from an atomic or molecular orbital. There are still open questions about how the relevant processes unfold in time. Scientists from the attoworld team at the Max Planck Institute of Quantum Optics and the Ludwig Maximilian University of Munich have now made a direct observation of how the optical properties of solids evolve after 1-femtosecond-scale photoinjection. In this video, Vladislav Yakovlev reports on these groundbreaking attosecond experiments published in the scientific journal Nature.
