Scanning tunnelling microscopy and spectroscopy of MgB2
Experiments of the scanning tunnelling microscopy and spectroscopy (STM/STS) have been carried out on the layered superconductor MgB2 with Tc = 39 K. The measurements were done at 5 K using a Pt-Ir tip and the single-crystal grain. The STM images show characteristic hexagonal patterns with the distances of nearest neighbour atoms to be 0.3 – 0.35 nm and 0.15 – 0.2 nm, respectively, which are co...
متن کاملInsulators at the ultrathin limit: electronic structure studied by scanning tunnelling microscopy and scanning tunnelling spectroscopy
Considerable progress has been made recently, using scanning tunnelling microscopy (STM), scanning tunnelling spectroscopy (STS) and local density functional theory (DFT), in examining the atomic structure and electronic properties of ultrathin insulating films. This article reviews pertinent results to date with special emphasis on ultrathin MgO films on Ag(001) surfaces. Using STS, the layer-...
متن کاملScanning tunnelling microscopy of suspended graphene.
Suspended graphene has been studied by STM for the first time. Atomic resolution on mono- and bi-layer graphene samples has been obtained after ridding the graphene surface of contamination via high-temperature annealing. Static local corrugations (ripples) have been observed on both types of structures.
متن کاملScanning tunnelling microscopy studies of silicides
We review the topic of scanning tunnelling microscopy (STM) studies of silicides, with an emphasis on fundamental scientific issues that can be addressed using STM and ballistic-electron-emission microscopy (BEEM). The discussion is organized according to the topics of structure (atomic scale precursors, surface reconstructions, bulk structures, interfaces) kinetics and growth (direct atomic me...
متن کاملField Emission Microscopy, Spectroscopy,Scanning Electron Microscopy and Field Emission Phenomena from Graphene-like Structures
The presented paper gives a general overview of studies of field emission from carbon nanoclusters. The special attention has been given to the study of emission processes in the strong and super strong electric fields from graphene-like structures. The direct experiments have confirmed the phenomena of the low threshold field emission and explosive emission from carbon nanoclusters. Experiment...
