The Nature of CVC Nonlinearity in Low-Voltage Scanning Tunneling Spectroscopy of Semiconductors [PDF]

EPJ Web of Conferences, 2021
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]

Scanning, 2002
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

Beilstein Journal of Nanotechnology, 2015
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 ...

Lattice reconstruction induced multiple ultra-flat bands in twisted bilayer WSe2

Nature Communications, 2021
It was predicted that lattice reconstruction can lead to the emergence of multiple ultra-flat electronic bands in twisted bilayer transition metal dichalcogenides.

Scanning Tunneling Spectroscopy in MgB2

, 2001
We present scanning tunneling microscopy measurements of the surface of superconducting MgB2 with a critical temperature of 39K. In zero magnetic field the conductance spectra can be analyzed in terms of the standard BCS theory with a smearing parameter ...

Adsorption and reversible conformational change of a thiophene based molecule on Au(111)

Scientific Reports, 2023
We present a low temperature scanning tunneling microscope investigation of a prochiral thiophene-based molecule that self-assembles forming islands with different domains on the Au(111) surface.

Influence of the adsorption geometry of PTCDA on Ag(111) on the tip–molecule forces in non-contact atomic force microscopy

Beilstein Journal of Nanotechnology, 2014
Perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) adsorbed on a metal surface is a prototypical organic–anorganic interface. In the past, scanning tunneling microscopy and scanning tunneling spectroscopy studies of PTCDA adsorbed on Ag(111) have ...

Mapping the Dirac point in gated bilayer graphene

, 2009
We have performed low temperature scanning tunneling spectroscopy measurements on exfoliated bilayer graphene on SiO2. By varying the back gate voltage we observed a linear shift of the Dirac point and an opening of a band gap due to the perpendicular ...

Resonant Electron Tunneling Induces Isomerization of π‐Expanded Oligothiophene Macrocycles in a 2D Crystal

Advanced Science, 2022
Macrocyclic oligothiophenes and their π‐expanded derivatives constitute versatile building blocks for the design of (supra)molecularly engineered active interfaces, owing to their structural, chemical, and optoelectronic properties.
