Free Electron Theory for Thin Metal Films
Philip B. Allen
Quantum free electrons, i.e. plane waves, with wavevector k, and occupancy constrained by the Pauli exclusion principle, are explained in all solid state physics texts. Although ov…
Recovering hidden Bloch character: Unfolding Electrons, Phonons, and Slabs
P. B. Allen, T. Berlijn, D. A. Casavant +1
For a quantum state, or classical harmonic normal mode, of a system of spatial periodicity "R", Bloch character is encoded in a wavevector "K". One can ask whether this state has p…
A Spin-Resolved Photoemission Study of Photohole Lifetimes in Ferromagnetic Gadolinium
A. V. Fedorov, T. Valla, F. Liu +3
High resolution spin-resolved photoemission is used to probe the properties of a Gd(0001) surface state. The state shows both a spin-mixing behavior reflecting the exchange of magn…
Anharmonic Decay of Vibrational States in Amorphous Silicon
Jaroslav Fabian, Philip B. Allen
Anharmonic decay rates are calculated for a realistic atomic model of amorphous silicon. The results show that the vibrational states decay on picosecond timescales and follow the…
