Spectroscopic characterisation of high dielectric constant materials on semiconducting surfaces
In this work, various insulator/semiconductor interfaces on silicon, gallium arsenide (GaAs) and germanium have been studied by photoemission spectroscopy. Where possible, these interfaces were then tested electrically after the formation of capacitor structures. Each system presents its own unique …

Scanning tunneling microscopy and spectroscopy of graphene on semiconducting surfaces
… interaction for graphene on several different semiconducting substrates in ultrahigh vacuum (UHV). The Si(100) – 2×1:H, GaAs(110), InAs(110), and Si(111) – 7×7 surfaces used in this study were prepared in the UHV-STM chamber. We deposited monolayer and bilayer graphene features on the surfaces …

Integration of Single -Walled Carbon Nanotubes With Gallium Arsenide(110) and Indium Arsenide(110) Surfaces: A Scanning Tunneling Microscopy Study
In an effort to better elucidate the influence of semiconducting surfaces on supported carbon nanotubes, we have used scanning tunneling microscopy (STM) and spectroscopy (STS) to investigate the physical and electronic behavior of single-walled carbon nanotubes (SWNTs) coupled to GaAs(110) and …
