Attosecond streaking of photoelectrons emitted from metal surfaces
Boyan Obreshkov
We numerically investigate attosecond streaking time delays in the photoemission of valence and 2p core electrons of aluminum surface. We find that electron emission from the core…

Field emission from metal surfaces in the Thomas-Fermi-von-Weizsäcker model
Boyan Obreshkov, Bruno Lepetit
We evaluate the electron emission current density from jellium metallic surfaces in the Thomas-Fermi-von-Weizsäcker approximation. We implement the weighted density approximation (…
