Research Interests

I am an experimental electron microscopist with a particular interest in the investigation of relationships between structure, properties and applications in novel materials. My research interest may be summirised as follows:

  • Structural characterization of semiconductor materials using electron microscopy techniques: high resolution TEM, conventional TEM, STEM and associated techniques.
  • Electron Energy Loss Spectroscopy (EELS), in particular plasmon excitations.
  • Developing new analysis techniques through the use of the latest image and spectrum processing techniques.
  • Thin films and nanostructures, particularly semiconductor such as III-V-Sb, III-Nitrides, SiC and related materials.
  • Piezoelectric, ferroelectric and multiferroic materials.
  • Polarization and phase mapping at the nanometre scale in ceramic materials.
  • Microstructural phase transformations as a function of temperature and applied electric field.
  • Domain switching in ferroelectric thin films.
  • Semiconductor nanowires
  • 2D Semiconductors

Short Biography

I graduated in Chemical Sciences from the University of Granada (Spain) in 1996 and obtained my PhD, "Structural Characterisation of GaN-based heteroepitaxial systems", with highly Honorific distintion from the University of Cadiz in 2001. During this period I was also a visiting researcher at the EPFL-CIME Microscopie electronique in Laussane (Switzerland) and at The Institut des Sciences de la Matiere et du Rayonnement in Caen (France), where I subsequently spent a year as a research assistant continuing my work on III-Nitride materials on Si(111) and sapphire. This was followed by two years as a research fellow in the Materials Science department at Liverpool University working of strain measurements in STEM images (obtained in the SuperSTEM at Daresbury labs) and low-loss EELS spectroscopy in semiconductor materials. In 2005, I was awarded an individual 3+(2) years fellowship from Junta de Andalucia (Spain) on a competitive, peer-reviewed basis to develop characterization methodologies at nanometric scale in semiconductor materials. In September 2009, I was appointed as a Science City Senior Research Fellow in Physics at Warwick University, being part of the Advaced Materials theme. I also hold an Honorary Research Fellow position in the School of Physics and Astronomy in Birmingham University from October 2009. Through these years I have been collaborating with world-leading groups using advanced microscopy techniques both to determine defect structure in materials and the challenging and technologically relevant problem of determining strain and composition at nanometer scale.


This year I will be teaching part of the couse entitled Introduction to Microscopy.
