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.

Teaching

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