Preparation and photoemission investigation of bulk-like a-Mn films on W(110)
Abstract
We report the successful stabilization of a thick bulk-like, distorted α-Mn film with (110) orientation on a W(110) substrate. The observed (3×3) overstructure for the Mn film with respect to the original W(110) low-energy electron diffraction pattern is consistent with the presented structure model. The possibility to stabilize such a pseudomorphic Mn film is supported by density functional total energy calculations. Angle-resolved photoemission spectra of the stabilized α-Mn(110) film show weak dispersions of the valence band electronic states in accordance with the large unit cell.
