Stereoisomeric selection upon adsorption: A structural and optical study of curcuminoid derivatives on ultrathin films of KCl on Au(111) and on bulk KCl(001)

Par dans Axe 4 Étiquette Axe 4

We present a combined scanning tunneling microscopy (STM), noncontact atomic force microscopy (nc- AFM), and differential reflectance spectroscopy (DRS) study aiming at the characterization of the relationship between structural and…

Dual-heterodyne Kelvin probe force microscopy

Par dans Axe 4 Étiquette Axe 4

We present a new open-loop implementation of Kelvin probe force microscopy (KPFM) that provides access to the Fourier spectrum of the time-periodic surface electrostatic potential generated under optical (or electrical)…

Highly Conductive Tungsten Suboxide Nanotubes.

Par dans Axe 4 Étiquette Axe 4

We demonstrate a high electron conductivity (>100 S/cm and up to 1000 S/cm) of tungsten suboxide W(18)O(52.4-52.9) (or equivalently WO(2.91-2.94)) nanotubes (2-3 nm in diameter, ∼ µm long). The conductivity…

Observation of Kekulé vortices induced in graphene by hydrogen adatoms

Par dans Axe 4 Étiquette Axe 4

Fractional charges are one of the wonders of the fractional quantum Hall effect. Fractional excitations are also anticipated in two-dimensional crystals of non-interacting electrons under time-reversal symmetry,  as bound states…

Characterizing the Water-Forming Reaction on Graphite- and Ceria-Supported Palladium Nanoparticles and Nanoislands by the Work Function

Par dans Axe 4 Étiquette Axe 4

The water-forming reaction (WFR) between oxygen and hydrogen on metal surfaces is an important reaction in heterogeneous catalysis. Related research mostly focused on crystalline metal surfaces and thick films; however,…

A simple KPFM-based approach for electrostatic- free topographic measurements: the case of MoS2 on SiO2

Par dans Axe 4

A simple implementation of Kelvin probe force microscopy (KPFM) is reported that enables recording topographic images in the absence of any component of the electrostatic force (including the static term).…

Hidden surface photovoltages revealed by pump probe KPFM

Par dans Axe 4

We use pump-probe Kelvin probe force microscopy (pp-KPFM) in combination with non-contact atomic force microscopy (nc-AFM) under ultrahigh vacuum, to investigate the nature of the light-induced surface potential dynamics in…

High-temperature oxidation and reduction of the inverse ceria/Cu(111) catalyst characterized by LEED, STM, nc-AFM and KPFM

Par dans Axe 4

The inverse catalyst 'cerium oxide (ceria) on copper' has attracted much interest in recent time because of its promising catalytic activity in the water–gas-shift reaction and the hydrogenation of CO2.…

Collective amplification of nearby nanoparticles in the Coulomb blockade restricted charging of a single nanoparticle

Par dans Axe 4, Axe 5

The characterization of charges in oxide supported metal nanoparticles (NP) is of high interest in research fields like heterogeneous catalysis and microelectronics. A general desire is to manipulate the charge…

Role of the structure and reactivity of Cu and Ag surfaces in the formation of a 2D Metal–Hexahydroxytriphenylene network

Par dans Axe 4, Axe 5

We have investigated the role played by the atomic structure and reactivity of the supporting Ag(111) and Cu(111) surfaces on the formation of 2D metal–organic networks (2D-MONs) involving metal adatom…
