Graphene has so far demonstrated remarkable properties, making it increasingly interesting for ultrafast electronic applications. Here, the authors show that, when probed by a highly charged ion, freestanding graphene is able to provide dozens of ele

In this joint experimental and theoretical study we demonstrate coherent control of the optical field emission and electron transport in plasmonic gaps subjected to intense single-cycle laser pulses. Our results show that an external THz field or a m

Publikováno v: The 22nd International Conference on Ultrafast Phenomena 2020.
Angle resolved spectra of photoelectrons generated by multiphoton ionization in the presence of THz-light fields were measured. We observed a strong electron modulation for different THz phases, which we attribute to momentum transfers caused by resc

Fast retrieval of temporal characteristics of FEL pulses using streaking by THz field
Autor: I. P. Sazhina, Nikolay M. Kabachnik, Andrey K. Kazansky
Publikováno v: Optics express. 27(9)
A simple and very fast method for reconstruction of temporal structure of linearly polarized FEL pulses from the THz streaking spectra of photoelectrons is suggested. The method is based on a quantum mechanical approach within the strong-field approx

Photoemission time versus streaking delay in attosecond time-resolved solid state photo-emission
Autor: Andrey K. Kazansky, Ulrich Heinzmann, Walter Enns, Walter Pfeiffer, Andreas Gebauer, Sergej Neb
Publikováno v: EPJ Web of Conferences, Vol 205, p 02019 (2019)
Time-dependent Schrodinger equation simulations for a one-dimensional model potential reveal that the delay extracted from a streaking spectrogram does not reflect the photoemission time if the streaking field inside the solid cannot be neglected.

Publikováno v: EPJ Web of Conferences, Vol 205, p 02016 (2019)
Attosecond time-resolved photoemission from the differently terminated BiTeCl surfaces yield a photoelectron streaking that cannot be explained by bulk propagation effects alone. Instead, the atomic scale electronic structure and dynamical screening
