Assembly of Robust Holmium-Directed 2D Metal-Organic Coordination Complexes and Networks on the Ag(100) Surface

We describe the formation of lanthanide-organic coordination networks and complexes under ultra-high-vacuum conditions on a clean Ag(100) surface. The structures comprise single Ho atoms as coordination centers and 1,4-benzenedicarboxylate (from terephtali ...

Clean, cleaved surfaces of the photovoltaic perovskite

László Forró, Henrik Moodysson Rønnow, Jeremy Luterbacher, Endre Horvath, Jan Hugo Dil, Luka Ciric, Bálint Náfrádi, Stefan Peter Muff, Andrew Patton Weber, Márton Kollár, Benjamin Pierre Le Monnier

The surface of a material is not only a window into its bulk physical properties, but also hosts unique phenomena important for understanding the properties of a solid as a whole. Surface sensitive techniques, like ARPES (Angle-resolved photoemission spect ...

Monitoring Charge Carrier Dynamics at Atomic Length Scales by STM-induced Luminescence

Christoph Grosse

The goal of this thesis is the combination of the high spatial resolution of scanning tunneling microscopy (STM) with the high temporal resolution of optical spectroscopy, by monitoring the light emitted from the tunnel junction. Two complementary techniqu ...

Van der Waals interactions in the self-assembly of 5-amino[6]helicene on Cu(100) and Au(111)

Magalí Alejandra Lingenfelder

A combination of Scanning Tunnelling Microscopy and Density Functional Theory simulations highlights the role of van der Waals interactions in the self-assembly of an aminohelicene on Cu(100) and Au(111). ...

Convergent and divergent two-dimensional coordination networks formed through substrate-activated or quenched alkynyl ligation

Klaus Kern, Sebastian Stepanow, Christopher Seiji Kley

Metal coordination assemblies of the symmetric bi-functional 4,4'-di-(1,4-buta-1,3-diynyl)-benzoic acid are investigated by scanning tunnelling microscopy on metal surfaces. The formation of long-range ordered, short-range disordered and random phases depe ...

Effect of vanadium addition on the microstructure and mechanical properties of the ODS ferritic steels

Nadine Baluc, Zbigniew Oksiuta

In this work, the effects of vanadium addition in the range of 0.3-3% (in weight percent) for an oxide dispersion strengthened reduced activation ferritic (ODS RAF) steel were investigated. Samples of the V-modified steel have been prepared using elemental ...

Electron hopping at the Si(111):B-root 3 surface: Insight from local impurity spectroscopy

Cédric Tournier-Colletta

Boron vacancies at the Si( 111):B-root 3 surface are model systems in the comprehension of strongly correlated semiconductor surfaces. By using scanning tunneling spectroscopy, the origin of the single-vacancy electronic structure is addressed. It is shown ...

Polaronic Conductivity in the Photoinduced Phase of 1T-TaS2

Helmuth Berger

The transient optical conductivity of photoexcited 1T-TaS2 is determined over a three-order-of-magnitude frequency range. Prompt collapse and recovery of the Mott gap is observed. However, we find important differences between this transient metallic state ...
