Expanding the momentum field of view in angle-resolved photoemission systems with hemispherical analyzers
Expanding the momentum field of view in angle-resolved photoemission systems with hemispherical analyzers
In photoelectron spectroscopy, the measured electron momentum range is intrinsically related to the excitation photon energy. Low photon energies <10 eV are commonly encountered in laser-based photoemission and lead to a momentum range that is smaller than the Brillouin zones of most materials. This can become a limiting factor when …
