Atomic Level Structure-Property Relationship in a Spin-Orbit Mott insulator: Scanning Transmission Electron and Scanning Tunneling Microscopy Studies

Recent advances in atomic-scale spin-polarized scanning tunneling microscopy.

The Mn3N2 (010) surface has been studied using spin-polarized scanning tunneling microscopy at the atomic scale. The principle objective of this work is to elucidate the properties and potential of this technique to measure atomic-scale magnetic structures. The experimental approach involves the use of a combined molecular beam epitaxy/scanning tunneling microscopy system that allows the study ...

Atomic-Scale Spin-Polarized Scanning Tunneling Microscopy and Atomic Force Microscopy: a Review

Atomic-scale spin-polarized scanning tunneling microscopy is a powerful real-space technique for investigating the magnetic structure of surfaces. With its intrinsic lateral resolution capability, this technique can achieve atomic-scale resolved spin resolution of surfaces. Antiferromagnets, in particular, offer opportunities to test the spatial resolution of magnetism at ultimate length scales...

Atomic structure of carbon nanotubes from scanning tunneling microscopy

The atomic structure of a carbon nanotube can be described by its chiral angle and diameter and can be specified by a pair of lattice indices (n ,m). The electronic and mechanical properties are critically dependent on these indices. Scanning tunneling microscopy ~STM! is a useful tool to investigate carbon nanotubes since the atomic structure as well as the electronic properties of individual ...

Secondary Electron Trajectories in Scanning Tunneling Microscopy

The recently developed technique Scanning Tunneling Microscopy in the Field Emission regime (STM FE) is based on the Russell Young's topografiner technology [1]. The set-up is a no contacting device consisting of a sharp tip approached vertically to a conducting surface at variable distances and biased with a small voltage with respect to the surface (Figure 1). The system builds a junction acr...
