If you have a question about this talk, please contact Andrew Morris. Room changed In this seminar I will discuss the effect of anisotropic stress on electronic materials. For example, when the high-temperature superconductor YBa2Cu3O6.67 is compressed elastically by 1% along its a axis, the superconductivity is strongly suppressed, and charge density wave order appears. This change in electronic structure provides information on the interactions at play in this material, and that may contribute to its superconductivity. My group has developed methods to apply elastic strains of multiple per cent to single-crystal samples, using compact, piezoelectric-driven apparatus. In the next stage of our research we would like to explore the mechanical response of electronic materials, which will provide thermodynamic information on electronic states of matter. I would like to explore possibilities for technical collaboration in this area with the School of Materials and Metallurgy. One of our technical goals is to measure stress-strain curves of materials on a ~0.1 mm length scale, and over a wide range of temperatures including cryogenic temperatures, using compact apparatus. As it is getting into the grey part of the year I will keep my seminar to a length of 30-40 minutes. This talk is part of the School of Metallurgy and Materials Colloquia series.
