Nanolithography of the nanocorral structure of chemisorbed oxygen atoms on the graphitic lattice

Controlled atomic patterning is an attractive tool to fine tune properties of graphitic lattice. Several O-functionalized derivatives of graphitic lattice have been widely studied, e.g., graphene oxide, reduced graphene oxide, and functionalized carbon nan ...

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 ...

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 ...

Handedness-dependent quasiparticle interference in the two enantiomers of the topological chiral semimetal PdGa

Roland Widmer, Yi-Chiang Sun, Timur Kim, Samuel Thomas Stolz

It has recently been proposed that combining chirality with topological band theory results in a totally new class of fermions. Understanding how these unconventional quasiparticles propagate and interact remains largely unexplored so far. Here, we use sca ...

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 ...

Two-Dimensional Folding of Polypeptides into Molecular Nanostructures at Surfaces

Klaus Kern, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Herein we report the fabrication of molecular nanostructures on surfaces via two-dimensional (2D) folding of the nine amino acid peptide bradykinin. Soft-landing electrospray ion beam deposition in conjunction with high-resolution imaging by scanning tunne ...

Local resilience of the 1T-TiSe2 charge density wave to Ti self-doping

Helmuth Berger, Elia Razzoli, Philipp Aebi

In Ti-intercalated self-doped 1T-TiSe2 crystals, the charge density wave (CDW) superstructure induces two nonequivalent sites for Ti dopants. Recently, it has been shown that increasing Ti doping dramatically influences the CDW by breaking it into phase-sh ...

Atomic-Scale Imaging and Spectroscopy of Electroluminescence at Molecular Interfaces

Klaus Kern, Christoph Grosse

The conversion of electric power to light is an important scientific and technological challenge. Advanced experimental methods have provided access to explore the relevant microscopic processes at the nanometer scale. Here, we review state-of-the-art stud ...
