Extracting transport channel transmissions in scanning tunneling microscopy using superconducting excess current

Klaus Kern, Markus Etzkorn, Jacob Senkpiel

Transport through quantum coherent conductors, such as atomic junctions, is described by conduction channels. Information about the number of channels and their transmissions can be extracted from various sources, such as multiple Andreev reflections, dyna ...

Quantum dynamics in individual surface spins

Tobias Bilgeri

This thesis presents a combined experimental and theoretical study of the classical and quantum magnetization dynamics in single magnetic adatoms and molecules, and on the classical and quantum coherent control thereof. First, a detailed description of the ...

Single channel Josephson effect in a high transmission atomic contact

Klaus Kern, Markus Etzkorn, Jacob Senkpiel

The Josephson effect in scanning tunneling microscopy (STM) is an excellent tool to probe the properties of a superconductor on a local scale. We use atomic manipulation in a low temperature STM to create mesoscopic single channel contacts and study the Jo ...

Band Gap of Atomically Precise Graphene Nanoribbons as a Function of Ribbon Length and Termination

Christoph Leopold Talirz, Daniele Passerone

We study the band gap of finite NA=7 armchair graphene nanoribbons (7-AGNRs) on Au(111) through scanning tunneling microscopy/spectroscopy combined with density functional theory calculations. The band gap of 7-AGNRs with lengths of 8 nm and more is conver ...

High-quality single crystal diamond diffraction gratings fabricated by crystallographic etching

Olivier Martin, Niels Quack, Christian Santschi, Toralf Scharf, Teodoro Graziosi

We demonstrate a novel method for fabricating single crystal diamond diffraction gratings based on crystallographic etching that yields high-quality diffraction gratings from commercially available diamond plates. Both V-groove and rectangular gratin ...

Advances in High-Speed Atomic Force Microscopy

Adrian Pascal Nievergelt

High-speed atomic force microscopy (HS-AFM) is a scanning probe technique capable of recording processes at the nanometre scale in real time. By sequentially increasing the speed of individual microscope components, images of surfaces can be recorded at up ...

Nonstoichiometric 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 ...

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). ...

Quantitative Analysis of Scanning Tunneling Microscopy Images of Mixed-Ligand-Functionalized Nanoparticles

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez, Christoph Renner

Ligand-protected gold nanoparticles exhibit large local curvatures, features rapidly varying over small scales, and chemical heterogeneity. Their imaging by scanning tunneling microscopy (STM) can, in principle, provide direct information on the architectu ...

Miniature active damping stage for scanning probe applications in ultra high vacuum

Klaus Kern, Maximilian Assig, Carola Strasser

Scanning probe microscope (SPM) experiments demand a low vibration level to minimize the external influence on the measured signal. We present a miniature six-degree of freedom active damping stage based on a Gough-Stewart platform (hexapod) which is posit ...
