Dr Dimitra Georgiadou is currently a Research Associate in the Department of Materials, Imperial College London, in the group of Dr Martyn McLachlan. She works on an EPSRC Knowledge Transfer Secondment project, "RAFALITH", in close collaboration with PragmatIC, a UK-based SME that develops ultra low cost flexible electronics for smart packaging applications based on RFID and NFC technologies.

Dimitra received her PhD in Photochemistry/Organic Electronics from the National Technical University of Athens. Before that she obtained a Master’s Degree in Advanced Materials Science jointly from the Technical University of Munich, Ludvig-Maximilians University of Munich and University of Augsburg, while she also holds a Degree in Chemical Engineering from the National Technical University of Athens. She has gained industrial experience through internships in Procter&Gamble, Italy, and Schreiner Group, Germany.

Prior to this position ahe was a Marie Sklodowska-Curie Fellow in the Experimental Solid State Physics group (EXSS) at the Blackett Laboratory, Imperial College in the group of Professor Thomas Anthopoulos. The main focus of “A-LITHIA” project was to explore the scalability potential of a novel patterning technique, adhesion lithography (a-Lith), into large area flexible substrates. In parallel, she followed a multidisciplinary research trajectory aiming at the development of high performance co-planar nano-scale electronic devices on the a-Lith patterned substrates, the architectures and dimensions of which would be difficult or far too expensive to obtain with traditional patterning techniques (e.g. e-beam lithography).

Targeted proof-of-concept applications included:

  • radio frequency rectifying Schottky diodes
  • light-emitting diodes (LEDs)
  • photodetectors
  • non-volatile ferroelectric tunnel junction memories
  • molecular nano-junctions

Her previous research interests involve the following:

  • photochemical tuning of emission colour of fluorescent and phosphorescent emitters for application in polymer light-emitting diodes (PLEDs)
  • solution-processed organic and inorganic materials used as interfacial layers in PLEDs and organic photovoltaics (OPVs)
  • synthesis of mesoporous nanocrystalline TiO2 for application in dye sensitized solar cells (DSSCs)
