Research Interests

  • Synthesis, Characterization and Applications of  Layered Materials (Graphene, Boron Nitride, Molybdenum Disulfide)

 

Nanomaterials Lab

We are interested in studying the growth of different nanomaterials, mainly 2D atomic-films (like graphene, transition metal dichalcogenides, hexagonal boron nitride, etc.), and to explore their structure-property correlations.

 

Layered materials offer a wide variety of properties, from superconductors (NbSe2-at low T), metals or semi-metals (graphene, NbSe2, NbTe2, NbS2, VO2, etc.), semiconductors (MoS2, MoSe2, WS2, WSe2, etc.) and insulators (h-BN). Many exciting physical and chemical phenomena in these special materials depend on the number of layers, stacking order, composition and edge-structure and there is a strong scientific and technological interest in the understanding such dependence.

 

Our research focuses in the developing of new synthetic methodologies for the controlled formation of 2D layered materials at the single-layer level, explore their structure (phase, stacking order, composition, etc.) – properties correlation and to show their integration into functional devices (electrical, optoelectrical, sensors, etc.).
