Evidence for time-reversal symmetry breaking of the superconducting state near twin-boundary interfaces in FeSe revealed by scanning tunneling spectroscopy. [PDF]
Advanced imaging and spectroscopy techniques make it possible to investigate electronic states in superconductors. Scanning tunneling microscopy shows that time-reversal symmetry is broken at the crystallographic boundaries of superconducting FeSe.

Line and Point Defects in MoSe2 Bilayer Studied by Scanning Tunneling Microscopy and Spectroscopy. [PDF]
Bilayer (BL) MoSe2 films grown by molecular-beam epitaxy (MBE) are studied by scanning tunneling microscopy and spectroscopy (STM/S). Similar to monolayer (ML) films, networks of inversion domain boundary (DB) defects are observed both in the top and ...

Waveform-sequencing for scanning tunneling microscopy based pump-probe spectroscopy and pulsed-ESR
We present here the straightforward implementation of pump-probe methods into existing scanning tunneling microscopy (STM) systems. Our method uses the waveform-sequencing abilities of a standard arbitrary waveform generator (AWG) and a simple mechanical

Molecular-beam epitaxy of monolayer and bilayer WSe2: a scanning tunneling microscopy/spectroscopy study and deduction of exciton binding energy [PDF]
Interest in two-dimensional (2D) transition-metal dichalcogenides (TMDs) has prompted some recent efforts to grow ultrathin layers of these materials epitaxially using molecular-beam epitaxy (MBE). However, growths of monolayer (ML) and bilayer (BL) WSe2—

Zero-bias anomaly in one-dimensional ultrathin metallic nanowires
The electronic properties of ultrathin bimetallic Au/Ag nanowires with 2-3 nm in diameter were explored by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) at liquid-nitrogen temperature.

The Nature of CVC Nonlinearity in Low-Voltage Scanning Tunneling Spectroscopy of Semiconductors [PDF]
A new model of field emission in a scanning tunnelling microscope was developed. The model describes the tunnelling current from a surface of semiconductor (semimetal) and allows estimating the preexponential factor in the expression for the tunneling ...

Scanning tunneling microscope spectroscopy of polymers [PDF]
AbstractThis paper presents theoretical results on the relationship between density of states (DOS) and scanning tunneling microscope current‐voltage curves in polymers. We considered samples of linear hydrocarbons electrically grounded at one of their extremes.

Sub-monolayer film growth of a volatile lanthanide complex on metallic surfaces
We deposited a volatile lanthanide complex, tris(2,2,6,6-tetramethyl-3,5-heptanedionato)terbium(III), onto metal surfaces of Cu(111), Ag(111) and Au(111) in vacuum and observed well-ordered sub-monolayer films with low temperature (5 K) scanning ...

Characterization of single-molecule pentanedithiol junctions by inelastic electron tunneling spectroscopy and first-principles calculations [PDF]
We study pentanedithiol molecular junctions formed by means of the break-junction technique with a scanning tunneling microscope at low temperatures. Using inelastic electron tunneling spectroscopy and first-principles calculations, the response of the ...
