Abstract: The field of Oxide Electronics got its boost in the 1987-time frame with the invention of the Pulsed Laser Deposition process which enabled the rapid prototyping of virtually most multi component oxide films. Since then the research in this field has accelerated, several novel phenomena have been uncovered in oxides and their heterostructures and currently we are poised on the threshold for this field to take off commercially- though we have no clue as to where the breakthrough will come from. I will address this issue in terms of the evolving landscape of opportunities in the field of electronics, memory, photonics and Plasmonics.
I will also give examples of recent work in ferroelectric tunnel junctions where barriers consisting of just two unit cells of ferroelectrics seem to be adequate to provide decent ON/OFF ratios, a novel water splitting Niobate system with an unusually large carrier density despite its large 4.1 eV bandgap and the unusual interaction of electric fields with magnetism at oxide interfaces. If time permits I will also talk about a new organic memory system spin coated on ITO surfaces which shows extraordinary memory characteristics.
A short Biography
Prof. T. Venkatesan is currently the Director of the Nano Institute at the National University of Singapore (NUSNNI) where he is a Professor of ECE, Physics, MSE and NGS. He wore various hats at Bell Labs and Bellcore for about 17 years before becoming a Professor at University of Maryland for another 17 years. As the inventor of the pulsed laser deposition (PLD) process, he has over 710 papers and 30 patents in Oxide thin films (citations of 39,650 with a hirsch Index of 100-Google Scholar). He has graduated over 40 PhDs, 25 Post Docs and over 50 undergraduates. He is also the founder and Chairman of Neocera, a company specializing in PLD and magnetic field imaging systems. Close to 10 of the researchers (PhD students and Post Docs) under him have become entrepreneurs starting over 17 different commercial enterprises. He is a Fellow of the APS, winner of the Bellcore Award of excellence, Guest Professor at Tsinghua University, Winner of the George E. Pake Prize awarded by APS (2012), President’s gold medal of the Institute of Physics Singapore, Academician of the Asia Pacific Academy of Materials, Fellow of the World Innovation Forum, was a member of the Physics Policy Committee, the Board of Visitors at UMD and the Chairman, Forum of Industry and Applications of Physics at APS. He was awarded the outstanding alumnus award from two Indian Institute of Technologies- Kharagpur and Kanpur, India
