Experimental demonstration of a two-band superconducting state for lead using scanning tunneling spectroscopy. [PDF]

open access: yesPhysical Review Letters, 2014
The type I superconductor lead (Pb) has been theoretically predicted to be a two-band superconductor. We use scanning tunneling spectroscopy (STS) to resolve two superconducting gaps with an energy difference of 150  μeV. Tunneling into Pb(111), Pb(110),

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

open access: yesScientific 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.

Emergence of a coherent in-gap state in the SmB6 Kondo insulator revealed by scanning tunneling spectroscopy. [PDF]

open access: yesPhysical Review Letters, 2014
We use scanning tunneling microscopy to investigate the (001) surface of a cleaved SmB6 Kondo insulator. Variable temperature dI/dV spectroscopy up to 60 K reveals a gaplike density of state suppression around the Fermi level, which is due to the ...

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

open access: yesBeilstein 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 ...

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

open access: yesAdvanced 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.

Electronic band dispersion of graphene nanoribbons via Fourier-transformed scanning tunneling spectroscopy [PDF]

open access: yes, 2014
The electronic structure of atomically precise armchair graphene nanoribbons of width N=7 (7-AGNRs) are investigated by scanning tunneling spectroscopy (STS) on Au(111).

Scanning Tunneling Microscopy and Spectroscopy of Air Exposure Effects on Molecular Beam Epitaxy Grown WSe2 Monolayers and Bilayers.

open access: yesACS Nano, 2016
The effect of air exposure on 2H-WSe2/HOPG is determined via scanning tunneling microscopy (STM). WSe2 was grown by molecular beam epitaxy on highly oriented pyrolytic graphite (HOPG), and afterward, a Se adlayer was deposited in situ on WSe2/HOPG to ...

Mapping the Dirac point in gated bilayer graphene

open access: yes, 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 ...

Tunneling Spectroscopy and Vortex Imaging in Boron-Doped Diamond [PDF]

open access: yes, 2006
We present the first scanning tunneling spectroscopy study of single-crystalline boron doped diamond. The measurements were performed below 100 mK with a low temperature scanning tunneling microscope.
