Robert Barklie graduated from TCD in 1966 with a First Class Honours degree in Physics.He then moved to the Cavendish Laboratory in Cambridge University where he obtained a PhD in 1969.From 1969 to 1973 he was a Lecturer in the Physics Department at Makerere University in Uganda and from there he returned to the Cavendish Laboratory for a year as a Postdoctoral Fellow .In 1974 he was appointed a Lecturer in Physics at TCD and later a Senior Lecturer.He retired in September 2008 but continues to research and to be involved in some teaching .

Project Title
 Oxide Thin Films
From
2002
To
2007
Summary
Two projects are being undertaken - the first is the characterisation of defects in high k dielectrics and at their interface with silicon and the second is an investigation of the magnetic properties of ferromagnetic oxides. The further scaling down in the size of the type of electronic circuits used in microprocessors will shortly require the replacement of SiO2 as the gate dielectric in silicon MOSFETs ;it will need to be replaced with a material with a higher dielectric constant such as HfO2 or ZrO2.Since atomic defects in such materials or at their interface with silicon can degrade the device performance it is important to characterise such defects with a view to reducing their population and this is the aim of this project. The second project is to characterise the magnetic properties of ferromagnetic (or ferrimagnetic) thin films such as magnetite or doped ZnO.Such materials are being investigated because of their possible use in the field of Spintronics and the aim of this project is to characterise these materials using primarily the technique of Ferromagnetic Resonance.

Fellow of Trinity College Dublin 1993
Applications of the techniques of Electron Paramagnetic Resonance, Ferromagnetic Resonance and Electrically Detected Magnetic Resonance to the characterisation of atomic defects, ions , radicals etc with unpaired electron spin in a wide variety of materials. Current research is focused on 1) the characterisation of atomic defects in high k dielectrics on silicon and 2) the investigation of the magnetic properties of thin films of magnetite and other magnetic materials using primarily the technique of Ferromagnetic Resonance.
