"Oxide-free" tip for scanning tunneling microscopy [PDF]

open access: yes, 1987
We report a new tip for scanning tunneling microscopy and a tip repair procedure that allows one to reproducibly obtain atomic images of highly oriented pyrolytic graphite with previously inoperable tips.

Scanning Tunneling Microscopy and Spectroscopy of Supported Nanostructures

open access: yesCHIMIA, 2012
Recent advances in low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) have provided new opportunities for the investigation of the local geometric, electronic, magnetic, and optical properties of nanostructures.

Spectroscopic signature of the Stark-shifted Tamm-type surface state of La(0001)

open access: yesNew Journal of Physics, 2020
We have studied the Tamm-type surface state of La(0001) by tunneling spectroscopy within a wide range of tunneling currents from 0.1 nA to 8000 nA, thereby tuning the electric-field strength in a tip-vacuum-sample tunnel junction.

Noncontact lateral-force gradient measurement on Si(111)-7×7 surface with small-amplitude off-resonance atomic force microscopy [PDF]

open access: yes, 2009
In this work, the authors report on a quantitative investigation of lateral-force gradient and lateral force between a tungsten tip and Si(111)-(7×7) surface using combined noncontact lateral-force microscopy and scanning tunneling microscopy ...

Quantum dot scanning tunneling microscopy for Majorana bound states in continuum

open access: yesFrontiers in Physics, 2022
We propose a device composed of a quantum dot (QD) connected to a normal metal lead to detect Majorana bound states (MBSs), which are formed at the ends of a topological superconductor nanowire (TSNW) and coupled to the lead with spin-dependent ...

Scanning tunneling microscopy measurements of the spin Hall effect in tungsten films by using iron-coated tungsten tips

open access: yesAIP Advances, 2018
Scanning tunneling microscopy experiments using iron-coated tungsten tips and current-carrying tungsten films have been conducted. An asymmetry of the tunneling current with respect to the change of the direction of the bias current through a tungsten ...

Scanning Tunneling Microscopy and Tunneling Luminescence of the Surface of GaN Films Grown by Vapor Phase Epitaxy [PDF]

open access: yes, 1995
We report scanning tunneling microscopy (STM) images of surfaces of GaN films and the observation of luminescence from those films induced by highly spatially localized injection of electrons or holes using STM.

Sub-monolayer film growth of a volatile lanthanide complex on metallic surfaces

open access: yesBeilstein 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 ...

Josephson scanning tunneling microscopy

open access: yes, 2000
We propose a set of scanning tunneling microscopy experiments in which the surface of superconductor is scanned by a superconducting tip. Potential capabilities of such experimental setup are discussed.

Combined I(V) and dI(V)/dz scanning tunneling spectroscopy

open access: yesAIP Advances, 2018
We present a method to simultaneously record I(V) and dI(V)dz spectra in a scanning tunneling microscopy measurement, where I, V and z refer to the tunnel current, sample bias and tip-substrate separation, respectively.
