Scanning Tunneling Microscopy and Atomic Force Microscopy

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...

(2n × 1) Reconstructions of TiO2(011) Revealed by Noncontact Atomic Force Microscopy and Scanning Tunneling Microscopy

We have used noncontact atomic force microscopy (NC-AFM) and scanning tunneling microscopy (STM) to study the rutile TiO2(011) surface. A series of (2n × 1) reconstructions were observed, including two types of (4 × 1) reconstruction. High-resolution NC-AFM and STM images indicate that the (4 × 1)-α phase has the same structural elements as the more widely reported (2 × 1) reconstruction. An ar...

Combining Atomic Force Microscopy and Laser Scanning Confocal Microscopy

Introduction The visualisation of sample elements using various forms of microscopy relies not only on magnification but also contrast. As such, differing forms of microscopy offer different information about a sample. Laser scanning confocal microscopy (LSCM) provides information about the 3D location of a particular, labelled component within a sample and has the additional advantage of exclu...

Atomic Structures of Silicene Layers Grown on Ag(111): Scanning Tunneling Microscopy and Noncontact Atomic Force Microscopy Observations

Silicene, the considered equivalent of graphene for silicon, has been recently synthesized on Ag(111) surfaces. Following the tremendous success of graphene, silicene might further widen the horizon of two-dimensional materials with new allotropes artificially created. Due to stronger spin-orbit coupling, lower group symmetry and different chemistry compared to graphene, silicene presents many ...
