Scanning Tunneling Spectroscopy in MgB 2 [PDF]

Physica C: Superconductivity, 2002
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 ...

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.

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.

RF injection scanning tunneling spectroscopy of a superconducting NbSe2 surface [PDF]

Scientific Reports
NbSe2 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 ...

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 ...

Pseudodoping of Metallic Two-Dimensional Materials by The Supporting Substrates [PDF]

, 2018
We demonstrate how hybridization between a two-dimensional material and its substrate can lead to an apparent heavy doping, using the example of monolayer TaS$_2$ grown on Au(111).
