Comparison of the thermal stability of single Al2O3 layers and Al2O3/SiNx stacks for the surface passiviation of silicon

Veith, Boris; Werner, Florian; Zielke, Dimitri; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier BV, 2011)

We measure surface recombination velocities (SRVs) below 10 cm/s on low-resistivity (1.4 Ωcm) p-type crystalline silicon wafers passivated with plasma-assisted and thermal atomic layer deposited (ALD) aluminium oxide (Al2O3) ...
Correlated motion of electrons on the Au(111) surface: Anomalous acoustic surface-plasmon dispersion and single-particle excitations

Vattuone, L.; Smerieri, M.; Langer, Thomas; Tegenkamp, Christoph; Pfnür, Herbert; Silkin, V.M.; Chulkov, E.V.; Echenique, P.M.; Rocca, M. (College Park, MD : American Physical Society, 2013)

The linear dispersion of the low-dimensional acoustic surface plasmon (ASP) opens perspectives in energy conversion, transport, and confinement far below optical frequencies. Although the ASP exists in a wide class of ...
Effective passivation of crystalline silicon surfaces by ultrathin atomic-layer-deposited TiOx layers

Titova, V.; Veith-Wolf, B.; Startsev, D.; Schmidt, J. (London : Elsevier Ltd., 2017)

We characterize the surface passivation properties of ultrathin titanium oxide (TiOx) films deposited by atomic layer deposition (ALD) on crystalline silicon by means of carrier lifetime measurements. We compare different ...
Generation of ultrasmall nanostructures in oxide layers assisted by self-organization

Block, T.; Pfnür, Herbert (College Park, MD : American Institute of Physics, 2008)

We explored the structural limits of unconventional electron-beam lithography by directly writing with an electron beam into ultrathin SiO2 films. The obtained structures were analyzed by tunneling microscopy. The Auger ...
Implementation of full-area-deposited electron-selective TiOx layers into silicon solar cells

Titova, Valeriya; Schmidt, Jan (College Park, MD : American Institute of Physics, 2018)

We examine two different silicon solar cell designs featuring full-area electron-selective contacts based on ultrathin (2-3 nm) titanium oxide (TiOx) films deposited by atomic layer deposition. The first cell design applies ...
Reactivity and Stability of Ultrathin VOx Films on Pt(111) in Catalytic Methanol Oxidation

von Boehn, Bernhard; Scholtz, Lena; Imbihl, Ronald (Dordrecht : Springer Science + Business Media, 2020)

The growth of ultrathin layers of VOx (< 12 monolayers) on Pt(111) and the activity of these layers in catalytic methanol oxidation at 10−4 mbar have been studied with low-energy electron diffraction, Auger electron ...
Spin-resolved band structure of a densely packed Pb monolayer on Si(111)

Brand, C.; Muff, S.; Fanciulli, M.; Pfnür, Herbert; Tringides, M.C.; Dil, J.H.; Tegenkamp, Christoph (College Park, MD : American Physical Society, 2017)

Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure ...
Switchable nanometer contacts: Ultrathin Ag nanostructures on Si(100)

Gardinowski, G.; Schmeidel, J.; Pfnür, Herbert; Block, T.; Tegenkamp, Christoph (College Park, MD : American Institute of Physics, 2006)

The fabrication and characterization of metallic nanometer-sized gaps suitable for conductivity measurements of single molecules were studied. Controlled gap formation by electromigration (EM) is demonstrated in contiguous ...
