Two-dimensional materials are currently among the most intensively studied topics in
condensed matter physics because of their intriguing properties and the possibilities of …

We present a study of sulfur adsorption on bare Ir (111). Two well-defined superstructures
are found: a (3× 3) R 30° and ac (4× 2) S-adlayer. Moreover, we also investigate sulfur …

Intensive research has focused on harnessing the potential of graphene for electronic,
optoelectronic, and spintronic devices by generating a bandgap at the Dirac point and …

This chapter describes the work done by means of Scanning Tunneling Microscopy and
Spectroscopy on the characterization of graphene grown or deposited on different …

The structural properties of sulfur superstructures adsorbed on Ru (0001) have been widely
studied in the past. However, much less effort has been devoted to determine their electronic …

Graphene was first postulated theoretically by PR Wallace [1] as a theoretical construct to
help in the calculation of the band structure of graphite. Experimentally, graphene has been …
