Scanning tunnelling microscopy studies of silicides

Probing ultrafast spin dynamics with optical pump-probe scanning tunnelling microscopy.

Studies of spin dynamics in low-dimensional systems are important from both fundamental and practical points of view. Spin-polarized scanning tunnelling microscopy allows localized spin dynamics to be characterized and plays important roles in nanoscale science and technology. However, nanoscale analysis of the ultrafast dynamics of itinerant magnetism, as well as its localized characteristics,...

The study of silver nanoparticles by scanning electron microscopy, energy dispersive X-ray analysis and scanning tunnelling microscopy

The authors present results of studies on commercially available silver nanoparticles fabricated by Amepox Microelectronics and delivered in the form of silver powder. The studies were carried out by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and scanning tunnelling microscopy (STM). Chemical analysis performed with the use of EDX revealed that the powder contain...

Surface morphology of semiconducting iron silicides grown on Si( 111)

A surface roughness analysis of P-Fe%, films grown by solid phase epitaxy on Si(ll1) substrates is presented. The composition and stoichiometry of the silicides are determined by X-ray photoemission spectroscopy. Pinholes are detected in thick samples grown by the SPE method. Quantitative measurements of the roughness for different FeSi, thicknesses are based on scanning tunneling microscopy im...

Microwave absorption properties of Ni/(C, silicides) nanocapsules

The microwave absorption properties of Ni/(C, silicides) nanocapsules prepared by an arc discharge method have been studied. The composition and the microstructure of the Ni/(C, silicides) nanocapsules were determined by means of X-ray diffraction, X-ray photoelectric spectroscopy, and transmission electron microscope observations. Silicides, in the forms of SiOx and SiC, mainly exist in the sh...
