Ignacio Hernandez's main research interests are:




These materials show interesting optical properties. The aim is to understand physical electronic processes leading to absorption and emission of light and to improve their capabilities for devices such as LEDs (or OLEDs), phosphors, lasers, ampifying optical fibers, etc. Particular interest is devoted to organics, which allow for new advanced phenomena.
Energy transfer between groups in a material or molecule is one the most interesting electronic and optical phenomena. It plays a crucial role in phosphors and also in OLEDs, photovoltaics, medicine, biology (incl. photosynthesis), etc. One of the particular useful properties that can be studied is the conversion of radiation by addition or cutting of photons (upconversion and downconversion, respectively).
The role of intermolecular forces and the correlation of macroscopic physical-chemical properties and the microscopic nature and ordering of the atoms in materials are very important for designing new materials with advanced properties and for understanding the physics of the involved processes. Organic semiconductors, hybrids and nanoparticles allow to study different regimes and interactions such as interatomic, intermolecular and interdomain interactions.
Pressure is a unique tool to change the interatomic/intermolecular forces and distances. Moreover, it can also alter the geometry and symmetry of the materials at the microscopic scale. By means of a Diamond Anvil Cell or other high pressure devices, we can compress the material and study a number of microscopic and macroscopic properties via X-ray diffraction, Optical and Raman Spectroscopy, etc. Thus we can produce structural and micro-macro correlations, which would be otherwise inaccessible.
Carbon nanostructures such as Nanotubes and Graphene show extremely interesting mechanical and electronic properties. They can be used as prototype materials to study a number of effects involving the interaction of electronic structure and deformation (mechanical properties) at the nanoscale.
IH is open for collaborations in these and maybe other topics. Please enquire.
