Presentation Transcript

  1. … Multifunctional Heterostructures of Perovskite Structured MaterialsYayoi Takamura, University of California-Davis, DMR 0747896 A novel route for the development of new materials with properties tailored for next generation spintronic devices, sensors and solid oxide fuel cell, involves harnessing the unexpected physical phenomena that result from the changes in structure and chemistry which occur over nanometer scales at surfaces and interfaces. We have grown superlattice structures consisting of alternating layers of La0.7Sr0.3FeO3, La0.7Sr0.3MnO3, and/or La0.7Sr0.3CoO3 with sublayer thicknesses ranging from three to 18 unit cells by pulsed laser deposition. (right) Schematic of La0.7Sr0.3MnO3 (LSMO) / La0.7Sr0.3FeO3 (LSFO) superlattice structure, and (top) electrical resistivity as a function of temperature for varying sublayer thickness. We find that the balance between a number of interfacial phenomena (long- range dipole interactions, electronic reconstruction, and exchange interactions) strongly affects the overall magnetic and electrical characteristics of the superlattices. Therefore, their properties can be tailored by the choice of the sublayer material and its thickness.

  2. Multifunctional Heterostructures of Perovskite Structured MaterialsYayoi Takamura, University of California-Davis, DMR 0747896 As part of the broader impacts activities of this award, the PI has sponsored the UC Davis Science, Technology, Engineering, Mathematics (STEM) Transfer Day. This one-day event brings students from community colleges with Mathematics Engineering Science Achievement (MESA) programs from around California to UC Davis for a series of workshops and panels to learn about the academic and research opportunities available on campus. In particular, the program was designed with “active” interactions with faculty and students to counter the mis-perception that UC Davis is “theoretical”, not applied, and geared mainly towards medical research. The MESA programs are designed to aid educationally disadvantaged students to prepare for and graduate from a four-year college, and they have a proportionally higher percentage of students who are under-represented minorities, women, and first generation college attendees.
