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…
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)…
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…
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…
By moving individual Fe-Porphyrin-based molecules with the tip of Scanning Tunneling Microscope in the vicinity of a Br-atom containing elbow of the herringbone-reconstructed Au(111), we reversibly and continuously control their…
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 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).…
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…
Intrinsic optoelectronic properties of atomically precise graphene nanoribbons (GNRs) remain largely unexplored because of luminescence quenching effects that are due to the metallic substrate on which the ribbons are grown.…
Controlling the spatial distribution of dopants in graphene is the gateway to the realization of graphene-based electronic components. Here, it is shown that a submonolayer of self-assembled physisorbed molecules can…
