Worldwide research efforts on plasmons and metamaterials have been growing exponentially for the past ten years. Now, Antonio I. Fernández-Domínguez (IFIMAC), Francisco J. García-Vidal (IFIMAC & DIPC), and Luis Martín-Moreno (ICMA) discuss new directions for the future, such as the use of 2D materials and strong coupling phenomena, which are likely to shape the field […]
Graphene nanoribbons (GNRs), are strips of graphene with ultra-thin width (<50 nm). Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene. GNRs are very interesting structures, partly due to their attractive electronic properties. Those properties vary dramatically with changes in the […]

When we study for the first time the structure of the atom in high school we encounter for the first time the concept of quantum excitation. We learn that excitation is the process in which a nucleus, electron, atom, ion, or molecule acquires energy that raises it to a quantum state (the excited state) higher […]
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 […]
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 […]

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 […]
