Controlling photocurrent channels in scanning tunneling microscopy

open access: yesNew Journal of Physics, 2020
We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction curves

Probing Italy: A Scanning Probe Microscopy Storyline

open access: yesMicro, 2023
Starting from the late 1980’s, scanning probe microscopy has progressively diffused in Italy until today. In this paper, we provide a brief account of the main historical events and a current picture of the distribution of the active groups. A survey was

Nanoscale properties of lead halide perovskites by scanning tunneling microscopy

open access: yesEcoMat, 2021
Since the introduction of lead halide perovskites, tremendous progress has been made regarding their stability, reproducibility and durability. However, one of the issues that remains is related to the interfacial atomic structure arrangement and ...

Spin-Polarized Scanning Tunneling Microscopy: Breakthroughs and Highlights

open access: yesCHIMIA, 2012
The principle of scanning tunneling microscopy, an imaging method with atomic resolution capability invented by Binnig and Rohrer in 1982, can be adapted for surface magnetism studies by using magnetic probe tips.

Multi-Channel Exploration of O Adatom on TiO2(110) Surface by Scanning Probe Microscopy

open access: yesNanomaterials, 2020
We studied the O2 dissociated state under the different O2 exposed temperatures with atomic resolution by scanning probe microscopy (SPM) and imaged the O adatom by simultaneous atomic force microscopy (AFM)/scanning tunneling microscopy (STM).

Nanoscopic Filters as the Origin of d Wave Energy Gaps [PDF]

open access: yes, 2003
A ferroelastic nanoscopic checkerboard pattern of pseudo- and superconductive gaps has been resolved by scanning tunneling microscopy on BSCCO. Using this pattern one can derive [not assume] a macroscopic anisotropic d wave superconductive energy gap ...

Imaging Anyons with Scanning Tunneling Microscopy

open access: yesPhysical Review X, 2018
Anyons are exotic quasiparticles with fractional charge that can emerge as fundamental excitations of strongly interacting topological quantum phases of matter.

Imaging Pauli repulsion in scanning tunneling microscopy [PDF]

open access: yes, 2010
A scanning tunneling microscope (STM) has been equipped with a nanoscale force sensor and signal transducer composed of a single D2 molecule that is confined in the STM junction.

The Art of Catching and Probing Single Molecules

open access: yesCHIMIA, 2012
Probing the electronic properties of an individual molecule is a far from trivial task. In order to measure, for instance, the conductance of a single molecule, the molecule must be contacted by two nanoscopic electrodes.
