| الوصف: | A novel Bloch-waves based one-step theory of photoemission is developed within the augmented plane wave formalism. Implications of multi-Bloch-wave structure of photoelectron final states for band mapping are established. Interference between Bloch components of initial and final states leads to prominent spectral features with characteristic frequency dispersion experimentally observed in VSe2 and TiTe2. Interference effects together with a non-free-electron nature of final states strongly limit the applicability of the common direct transitions band mapping approach, making the tool of one-step analysis indispensable. Angle resolved photoemission (ARPES) is the most powerful tool to study electronic structure of crystals [1]. The basis for the interpretation of experimental results is provided by the one-step theory of photoemission [2], in which the photoelectron initial states are one-particle eigenstates of the semi-infinite crystal, and the final state is the time reversed LEED state |Φ〉. |
