Atomic Scale Observation of Chemical and Electronic Properties of Metal-Oxide Surfaces
Christian Alexander Stephan Dette
To meet the future global energy demand - an estimated additional 10 terawatts (TWs) per year in 2050 - a diversification of energy sources and fuels is needed. Solar energy represents a prominent alternative energy source. An important material for these ...
EPFL2016Band Alignment Engineering at Cu2O/ZnO Heterointerfaces
Michael Graetzel, Stanley David Tilley
Energy band alignments at heterointerfaces play a crucial role in defining the functionality of semiconductor devices, yet the search for material combinations with suitable band alignments remains a challenge for numerous applications. In this work, we de ...
Amer Chemical Soc2016Monitoring Charge Carrier Dynamics at Atomic Length Scales by STM-induced Luminescence
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 ...
EPFL2015Nonstoichiometric Low-Temperature Grown GaAs Nanowires
Anna Fontcuberta i Morral, Federico Matteini, Heidi Andrea Potts, Tao Xu
The structural and electronic properties of nonstoichiometric low-temperature grown GaAs nanowire shells have been investigated with scanning tunneling microscopy and spectroscopy, pump probe reflectivity, and cathodoluminescence measurements. The growth o ...
American Chemical Society2015Quantum engineering of spin and anisotropy in magnetic molecular junctions
Single molecule magnets and single spin centres can be individually addressed when coupled to contacts forming an electrical junction. To control and engineer the magnetism of quantum devices, it is necessary to quantify how the structural and chemical env ...
Nature Publishing Group2015Combined ARPES and STM study of Pb/Au(111) Moiré structure: One overlayer, two symmetries
Klaus Kern, Harald Brune, Marco Grioni, Alberto Crepaldi, Markus Etzkorn, Emmanouil Frantzeskakis
The structural and electronic properties of a Pb monolayer (ML) grown on Au(111) are investigated by scanning tunneling microscopy (STM) and angle resolved photoelectron spectroscopy (ARPES). We find an incommensurate Moire structure with an approximate (5 ...
Amer Physical Soc2013Observation of a two-dimensional electron gas at the surface of annealed SrTiO3 single crystals by scanning tunneling spectroscopy
An extensive surface characterization of hydrofluoric acid (HF) etched and annealed SrTiO3 single crystals, vacuum-annealed below 300 degrees C, reveals the formation of a two-dimensional electron gas (2DEG). A joint scanning tunneling spectroscopy and low ...
Amer Physical Soc2012Near Field Optical Microscopy Imaging with a Free Electron Laser in the 1-10 Micron Spectral Range: Overview and Perspectives
The need to image objects on increasingly finer scales and spatially localized specific molecules can be met by the combination of infrared, visible and Raman spectroscopy with scanning near-field microscopy, giving rise to a powerful nanospectroscopic too ...
2011Local spectroscopy of the Kondo lattice YbAl3: Seeing beyond the surface with scanning tunneling microscopy and spectroscopy
We report on an atomic-scale study of the Kondo lattice compound YbAl3 using scanning tunneling microscopy (STM) and spectroscopy (STS). An analysis of the surface orientation and structure is performed based on STM images containing more than one crystal ...
