Condensed-Matter Physics & Materials Science Seminar
"Thin-Film Alchemy: Using Epitaxial Engineering to Unleash the Hidden Properties of Oxides"
Presented by Darrell G. Schlom, Cornell University
Monday, May 15, 2017, 1:30 pm — Bldg. 734, ISB Conference Room 201 (upstairs)
Guided by theory, unparalleled properties—those of hidden ground states—are being unleashed by exploiting large strains in concert with the ability to precisely control dimensionality and stabilize metastable phases in epitaxial oxide heterostructures. For example, materials that are not ferroelectric or ferromagnetic in their unstrained state can be transmuted into materials that are both at the same time. Similarly, new tunable dielectrics with unparalleled performance have been created as well as a new single-phase multiferroic material where ferroelectricity and strong magnetic ordering are coupled near room-temperature. These are just three examples of the unparalleled properties—those of hidden ground states—being unleashed in epitaxial oxide heterostructures utilizing thin film alchemy
