Micro-object pose estimation with sim-to-real transfer learning using small dataset

Communications Physics, 2022
High-resolution scanning tunnelling microscopy is a state-of-the-art imaging technique at the nanometer scale. This work presents a novel deep learning approach for 3D pose estimation of micro/nano-objects, particularly useful in regimes of limited ...

Atomic-scale characterization of nitrogen-doped graphite: Effects of dopant nitrogen on the local electronic structure of the surrounding carbon atoms [PDF]

, 2012
We report the local atomic and electronic structure of a nitrogen-doped graphite surface by scanning tunnelling microscopy, scanning tunnelling spectroscopy, X-ray photoelectron spectroscopy, and first-principles calculations. The nitrogen-doped graphite

Electrochemical Scanning Tunneling Microscopy

CHIMIA, 2012
The electrochemical scanning tunneling microscope was the first tool for the investigation of solid–liquid interfaces that allowed in situ real space imaging of electrode surfaces at the atomic level. Therefore it quickly became an important addition to the repertoire of methods for the determination of the local surface structure as well as ...

Electron scattering in atomic force microscopy experiments [PDF]

, 2005
It has been shown that electron transitions, as measured in a scanning tunnelling microscope (STM), are related to chemical interactions in a tunnelling barrier.

Real-space observation of incommensurate spin density wave and coexisting charge density wave on Cr (001) surface

Nature Communications, 2022
Spin density waves are a spatial modulation of the spin, and can be either commensurate or incommensurate with the crystal lattice. Here, Hu et al. use spin-polarised scanning tunnelling microscopy to observe the incommensurate spin density wave on ...

Magnetic exchange coupling of a synthetic Co(II)-complex to a ferromagnetic Ni substrate [PDF]

, 2013
On-surface assembly of a spin-bearing and non-aromatic porphyrin-related synthetic Co(II)-complex on a ferromagnetic Ni thin film substrate and subsequent magnetic exchange interaction across the interface were studied by scanning tunnelling microscopy ...

Pauli's Principle in Probe Microscopy [PDF]

, 2014
Exceptionally clear images of intramolecular structure can be attained in dynamic force microscopy through the combination of a passivated tip apex and operation in what has become known as the "Pauli exclusion regime" of the tip-sample interaction.

STM and RHEED study of the Si(001)-c(8x8) surface [PDF]

, 2010
The Si(001) surface deoxidized by short annealing at T~925C in the ultrahigh vacuum molecular beam epitaxy chamber has been in situ investigated by high resolution scanning tunnelling microscopy (STM) and reflected high energy electron diffraction (RHEED)

Li@C60 as a multi-state molecular switch

Nature Communications, 2019
Molecular switches that can access more than just a few states are difficult to realize. Here, the authors use scanning tunnelling microscopy and spectroscopy to show that a surface-bound Li@C60 endofullerene can be switched between 14 molecular states ...
