Dictionary learning in Fourier-transform scanning tunneling spectroscopy [PDF]
Nature Communications, 2020 Aperiodic structure imaging suffers limitations when utilizing Fourier analysis. The authors report an algorithm that quantitatively overcomes these limitations based on nonconvex optimization, demonstrated by studying aperiodic structures via the phase ...

RF injection scanning tunneling spectroscopy of a superconducting NbSe2 surface [PDF]
Scientific ReportsNbSe2 is a transition metal dichalcogenide with a two-dimensional nature, showing superconducting (SC) and charge density properties. Moreover, a 1T phase can be made in the film, which has a different property from the bulk dominant 2 H phase, in which ...

Combined I(V) and dI(V)/dz scanning tunneling spectroscopy
AIP Advances, 2018 We present a method to simultaneously record I(V) and dI(V)dz spectra in a scanning tunneling microscopy measurement, where I, V and z refer to the tunnel current, sample bias and tip-substrate separation, respectively.

Closed-loop conductance scanning tunneling spectroscopy: demonstrating the equivalence to the open-loop alternative [PDF]
Beilstein Journal of Nanotechnology, 2015 We demonstrate the validity of using closed-loop z(V) conductance scanning tunneling spectroscopy (STS) measurements for the determination of the effective tunneling barrier by comparing them to more conventional open-loop I(z) measurements.

From a wide band gap to the superconducting proximity effect: Fe on Pb(111)
New Journal of Physics, 2023 Epitaxially grown Fe nanostructures on Pb(111) were studied by low-temperature scanning tunneling microscopy and spectroscopy. The deposited Fe assemblies are classified into two groups according to their electronic behavior close to the Fermi energy ...

The Art of Catching and Probing Single Molecules
CHIMIA, 2012 Probing the electronic properties of an individual molecule is a far from trivial task. In order to measure, for instance, the conductance of a single molecule, the molecule must be contacted by two nanoscopic electrodes.
