“…Interestingly, the chemical and physical properties of manganese oxide nanoparticles and ultrathin films appear to be substantially different from their bulk counterparts. For instance, Mn 3 O 4 thin films deposited on glass substrates showed very good sensitivity for UV emission, 8 since their band gap (2.3−3.7 eV) could be varied as a function film thickness, orientation, growth methods, and/or nanoparticles synthesis. 5,9 Some studies have already addressed the correlation among the electronic, the magnetic, and the structural properties of oxide ultrathin films with the growth conditions (oxygen partial pressure p(O 2 ), substrate temperature, and postannealing conditions).…”

We investigated the electronic and the structural properties of Mn 3 O 4 thin films grown on Cu(111) as a function of preparation conditions (oxygen partial pressure and thickness). Mn 3 O 4 films are grown at oxygen partial pressure of 5 × 10 −7 mbar and displayed a (110) preferential plane orientation arranged in different spatial domains to better adapt to Cu(111) lattice parameters. The relative angle between the domains varies as the film thickness increases. At the Mn 3 O 4 /Cu(111) interface, the valence band is strongly perturbed by the contribution of Cu 3d states that modify the Mn 3d electronic configuration. As a consequence, Mn 3s and Mn 2p core level spectra present characteristic new line shapes that were explained within the core-level relaxation framework. At variance with other metal substrates used for stabilizing manganese oxides thin films, the copper presents a 3d electronic distribution strongly overlapping the Mn 3d orbital and consequently affecting the overall electronic properties at the contact layer.
