Attosecond coherent manipulation of electrons in tunneling microscopy
Nanoelectronic devices operating in the quantum regime require coherent manipulation and control over electrons at atomic length and time scales. We demonstrate coherent control over electrons in a tunnel junction of a scanning tunneling microscope by mean ...
AMER ASSOC ADVANCEMENT SCIENCE2020Scanning Probe-Directed Assembly and Rapid Chemical Writing Using Nanoscopic Flow of Phospholipids
Nanofluidic systems offer a huge potential for discovery of new molecular transport and chemical phenomena that can be employed for future technologies. Herein, we report on the transport behavior of surface-reactive compounds in a nanometer-scale flow of ...
AMER CHEMICAL SOC2019Three-dimensional imaging of integrated circuits with macro- to nanoscale zoom
Gabriel Aeppli, Manuel Guizar Sicairos, Christian David, Michal Odstrcil
The imaging of integrated circuits across different length scales is required for failure analysis, design validation and quality control. At present, such inspection is accomplished using a hierarchy of different probes, from optical microscopy on the mil ...
NATURE PUBLISHING GROUP20192-D assembly of supramolecular nanoarchitectures on Mg(0001)
Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto, Bart Willem Stel, Daniel Eduardo Hurtado Salinas
In this work, a Mg(0001) single crystal is used as a novel template to grow 2D supramolecular nano-architectures. By using scanning tunnelling microscopy (STM) and high-resolution X-ray photoemission spectroscopy (HR-XPS), the formation of either a homo-mo ...
ROYAL SOC CHEMISTRY2019Point-of-care amperometric determination of L-dopa using an inkjet-printed carbon nanotube electrode modified with dandelion-like MnO2 microspheres
Hubert Girault, Andreas Stephan Lesch, Milica Jovic
An electrochemical sensor is described for the determination of L-dopa (levodopa; 3,4-dihydroxyphenylalanine). An inkjet-printed carbon nanotube (IJPCNT) electrode was modified with manganese dioxide microspheres by drop-casting. They coating was character ...
2019Assembly 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 ...
AMER CHEMICAL SOC2018Catalytic amino acid production from biomass-derived intermediates
Paul Joseph Dyson, Ning Yan, Yefeng Wang, Shunlin Zhang, Yu Han
Amino acids are the building blocks for protein biosynthesis and find use in myriad industrial applications including in food for humans, in animal feed, and as precursors for bio-based plastics, among others. However, the development of efficient chemical ...
National Academy of Sciences2018Scanning tunneling microscopy on large bio-molecular systems on surfaces
The ever growing demand for the development of new technologies and materials has led to extensive studies inspired by biological functional complexes. Peptides with their outstanding ability to efficiently self-assemble can express a broad spectrum of int ...
EPFL2017Construction of a low temperature STM and studies of large molecular systems
Several aspects in the field of molecular self assembly are addressed in this thesis. Thanks to the scanning tunnelling microscope (STM), structural, electronic and magnetic properties on surfaces can be studied down to the size of a single atom. In this t ...
EPFL2016Localized electronic states at grain boundaries on the surface of graphene and graphite
Oleg Yazyev, Gabriel Albert Autes
Recent advances in large-scale synthesis of graphene and other 2D materials have underscored the importance of local defects such as dislocations and grain boundaries (GBs), and especially their tendency to alter the electronic properties of the material. ...
