Author: María A. Izquierdo-Morelos is a Ph.D. student (ITN-EJD-TCCM) at University of Groningen Over the past several decades researchers have thought how materials and device architectures can efficiently convert solar radiation into electrical power through the photovoltaic effect. Those efforts have led to different methods and processes to produce green energy. In this context, organic […]
Author: Stefano Battaglia is a Ph.D. student (ITN-EJD-TCCM) at Université de Toulouse III Since the Nobel Prize in Physics was awarded in 2010 to Andre Geim and Konstantin Novoselov for groundbreaking discoveries on the two-dimensional material graphene, the research in low-dimensional carbon nanostructures has seen an incredible increase of interest. Among the different types of […]
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 field-effect transistor (GFET), still remains a promising candidate for applications in flexible electronic circuits. An essential […]
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 as one of the alternative and sustainable energy sources has a potential to replace fossil […]
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 6.028×10 23 . Let’s say that it is more or less the quantity of hydrogen atoms contained in 1 gram. This trend is supposed to […]
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 are non-bonding in the ground state. Thus, excimers can be considered evanescent quasi-particles that typically […]
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 backplate of the instrument is covered with flour or sand, and bowed until it reached resonance […]

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 gap (graphene is gapless). However, an exhaustive experimental search has been inconclusive, resulting in doubts […]

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 2DESs at surfaces or interfaces and their interplay with magnetic degrees of freedom may open […]
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 Spectroscopy Laboratory, where she focused on the spectroscopic characterization of photoactive nanomaterials based on energy […]
