Invited Research Lecture on Fundamental Properties of TM Nitrides and Design Strategies for Growth of Self-organized Nitride Nanostructures by Prof Joe Greene, University of Illinois
Date: 03 Apr 2012 - 03 Apr 2012
Venue: Auditorium, Level 3, SIMTech Tower Block, 71 Nanyang Drive, Singapore 638075
The talk will present the latest studies on transition metal nitrides and their potential applications. The extreme range of materials properties available in transition metal nitrides and related systems can be enhanced through the formation of self-organised superhard nanostructures consisting of commensurate nanolamellae, nanocolumns, nanospheres, and nanopipes. Self-organisation strategies include controlled phase separation, surface-induced spinodal decomposition, surface segregation-induced renucleation, strain-induced roughening, surface anisotropy, and dynamic resputter yield amplification. As an example, the Ti-B-N system, exhibiting a deep miscibility gap in the ternary phase diagram, is used as an archetype to probe reaction paths leading to the directed self-organized growth of "intelligent" high-temperature nanostructures (e.g., the hardness actually increases with temperature).
10.00am Presentation by Professor Joe Greene

Professor Joe Greene obtained his Ph.D. in Materials Science from the University of Southern California in 1971 and joined the Materials Science Department at the University of Illinois. He became Full Professor in 1979 and is presently Head of the Electronic Materials Division at Illinois and Chaired Professor of Physics at Linkoping University, Sweden.
The focus of Joe's research has been the development of an atomic level understanding of adatom/surface interactions during the dynamic process of vapor-phase crystal growth in order to controllably manipulate microchemistry, microstructure, and, hence, physical properties. His work has involved film growth by all forms of sputter deposition, MBE, CVD, MOCVD, and ALE. In particular, he has used energetic accelerated condensing species and photochemistry as probes as well as to stimulate surface reactions that do not proceed thermally. He has developed ultra-high vacuum hybrid deposition techniques for the growth of epitaxial metastable phases as well as for low-temperature atomic-layer epitaxy techniques with self-limited kinetics.
Apart from other involvements, Joe has served as the Editor of CRC Critical Reviews in Solid State and Materials Sciences and is currently Editor-in-Chief of Thin Solid Films.
