We used scanning tunneling microscopy to investigate graphene formation on an SiC-on-insulator (SiC-OI) substrate. Annealing of an SiC-OI substrate with an SiC thickness of 1500 nm produced a graphene layer on the SiC surface. When the thickness of the SiC film was 5 nm, a graphene layer was not...

Ultra-thin Pb films with magic thicknesses of 2 monolayer (ML), 4 ML and 6 ML were prepared of atomically flat on the substrate of Si(111)-α-√3 × √3 (or SIC phase) at 145 K. Their surface morphologies and stability were studied by low temperature scanning tunneling microscopy and...

We have studied the superconductivity of Pb ultra-thin films with thickness from 1 monolayer (ML) to 7 ML grown on Si(111) by molecular beam epitaxy. In situ low temperature scanning tunneling spectroscopy (STS) and angle-resolved photoemission spectroscopy (ARPES) measurements were performed on...

The electrochemical formation and reduction of O-layers on gold (111) films in 1 m sulfuric acid under different potentiodynamic routines are investigated utilizing in situ scanning tunneling microscopy. The surface dynamics is interpreted considering the anodic and cathodic reaction pathways...

We report the reaction dynamics of the Bi-line structure (BLS) with copper-phthalocyanine (CuPc)molecules as well as hydrogen and Ag atoms on Si(100) surfaces observed by scanning tunneling microscopy. Co-adsorption of hydrogen and Ag on the Si(100) surface with BLSs brought about agglomeration...

Tunneling spectra of InAs nanocrystals anchored to gold via linker molecules or deposited onto graphite were measured using scanning tunneling microscopy, in a double-barrier tunnel-junction configuration. The effects of the junction symmetry on the tunneling spectra, due to both the voltage...
