Epitaxial growth of MnO/Ag() films

Monolayer alkali and transition-metal monoxides: MgO, CaO, MnO, and NiO

“…Epitaxial growth of MnO films has been reported on Ag(001) substrate and Pd(100) single-crystal surface. 20,21 Nickel oxide (NiO) thin-films (p-type oxide semiconductor) can also be deposited on a glass substrate using an inexpensive spray pyrolysis technique (SPT). 16,22,23 Moreover, the NiO layer insertion between the active organic layer showed cell power conversion efficiencies as high as 5.2%.…”

Two-dimensional manganese oxide nanolayers on Pd(100): the surface phase diagram

“…As for other transition metal oxide materials, thin films of manganese oxides supported on metal substrates bear promise for technological use and fundamental scientific studies. Thin films of MnO have been prepared with epitaxial order by various deposition methods on different noble metal single crystal surfaces, such as Ag(001) [7], Rh(100) [8], and Pt(111) [9,10] surfaces. Recently, we have grown epitaxial MnO films on Pd(100) with either (100) or (111) surface orientation [11], the orientation depending on the specific kinetic parameters during growth.…”

Growth and structure of thin MnO films on Ag(001) in dependence on film thickness

“…The experiments were performed with a VG ESCALAB MkII spectrometer, which is designed for angular resolved electron spectroscopy, such as, e.g., XPD and LEED [6,[23][24][25]. The sample is mounted on a manipulator with two rotational degrees of freedom (polar angle h, azimuthal angle /), so that the k-space within the whole 2p hemisphere above the surface of the sample can be scanned by the fixed energy analyzer as shown in Fig.…”

“…A detailed description of the preparation and characterization of such MnO/Ag(0 0 1) films can be found in [6]. Briefly, epitaxial MnO/Ag(0 0 1) films can be prepared at room temperature by evaporating manganese within an oxygen atmosphere of about p(O 2 )=2 Â 10 À7 mbar, at evaporation rates of about 1 ML per minute, and subsequent annealing at 500 K (thin films) and 800 K (thick films).…”

“…In a former paper et al [6] the preparation of epitaxial thin MnO films has been demonstrated, whereby the structural order of the film and interface has been controlled by LEED and XPD. In the experiment LEED intensity profiles have been recorded and analysed, whereby a LEED I(V) analysis was not planned.…”
