Among the astonishing properties of graphene, a high mobility of the charge carriers has placed this material into the focus of intensive research efforts, aimed at developing high-speed graphene-based electronic devices. The first device of this family, a graphene […]

Author: Meilani Wibowo obtained her master’s degree at the University of Valencia, Spain. Currently she is a Ph.D. student (ITN-EJC TCCM) at the University of Groningen, the Netherlands, where she works on the improvement of organic photovoltaic devices. . Solar energy […]

Author: Tommaso Francese is a Ph.D. student (ITN-EJD-TCCM) at Universitat de Barcelona. Every year the amount of data produced is of the order of magnitude of the Avogadro’s constant, thus 6.028×1023. Let’s say that it is more or less the […]

A chemical compound or molecule consisting of two identical simpler molecules is a dimer. If one of the simpler molecules is excited while the other is in its ground, non-excited, state we talk about excimers. They are excited dimers which […]

Luthiers still use Chladni figures in the design and construction of acoustic instruments such as violins, guitars, and cellos. The technique invented by the German physicist and musician Ernst Chladni (1756–1827) shows the modes of vibration under forcing. The […]

Graphene is a two-dimensional allotrope of carbon made of hexagons. In February 2015, penta-graphene, only made of pentagons, was theoretically proposed as another two-dimensional allotrope of carbon . Apparently, it is dynamically, thermally, and mechanically stable, exhibiting a large band […]

Silicon surfaces of crystalline solids are part of conventional electronics, but their exploitation in novel materials combining two-dimensional electron states (2DESs) and magnetism, which play an important role in the development of next-generation electronics, still remains elusive. The appearance of […]

Author:. Leire Gartzia Rivero got a Chemistry degree and completed her Master studies in “New Materials” at the University of the Basque Country. She holds a Ph.D. in Materials Science and Technology obtained at the same university, in the Molecular […]

Nanoparticles of certain metals, like gold or silver, have attracted substantial interest in recent years owing to their ability to support localized surface plasmon resonances (collective oscillations of conduction electrons). These plasmonic excitations allow manipulation of light at the nanoscale […]

A phase may be defined as a homogeneous portion of a system that has uniform physical and chemical characteristics. Every pure material is considered to be a phase; so also is every solid, liquid, and gaseous solution. For example, a […]
