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 ...

Scanning tunneling spectroscopy in MgB2 [PDF]
Physica C: Superconductivity, 2003 We present extensive Scanning Tunneling Spectroscopy (STM/S) measurements at low temperatures in the multiband superconductor MgB$_2$. We find a similar behavior in single crystalline samples and in single grains, which clearly shows the partial superconducting density of states of both the $ $ and $ $ bands of this material. The superconducting gaps

Scanning tunneling spectroscopy of homooligonucleotides
Eurasian Journal of Physics and Functional Materials, 2023 Short single-stranded DNA molecules of two types, consisting of dC nucleotides only or dA nucleotides only, were immobilized onto the surface of mica and silver substrates and studied by scanning probe microscopy methods.

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 ...

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.

Spin excitations and correlations in scanning tunneling spectroscopy [PDF]
New Journal of Physics, 2015 In recent years inelastic spin-flip spectroscopy using a low-temperature scanning tunneling microscope has been a very successful tool for studying not only individual spins but also complex coupled systems. When these systems interact with the electrons

Automated Tip Conditioning for Scanning Tunneling Spectroscopy
The Journal of Physical Chemistry A, 2021 Scanning tunneling spectroscopy (STS), a technique that records the change in the tunneling current as a function of the bias (dI/dV) across the gap between a tip and the sample, is a powerful tool to characterize the electronic structure of single molecules and nanomaterials.
