CEM is realizing innovative science and materials discovery by engaging researchers from diverse backgrounds and disciplines in an enabling collaborative environment. This research is integrated with programs to nurture and train future scientists and technologists, to best communicate the excitement and benefits of materials science to the public. Innovation is responsible for much of America’s economic vitality; discovery of novel materials and phenomena stemming from condensed matter and materials research underlies technology that is the basis for much of that strength. CEM brings together three interdisciplinary teams that bring together the necessary expertise, approaches and tools needed to create and understand new materials and reveal new physical phenomena. CEM will also enhance existing user facilities, seed emerging research areas, collaborate internationally and work with national labs and industry.
CEM pays particular attention to including relatively untapped resources of women and underrepresented groups to ensure the strength of the scientific community at the heart of this endeavor. This enterprise integrates scientific research into programs to recruit, retain and teach diverse undergraduates, graduates, and postdocs. CEM’s focused plans will broaden the engagement of students and the public with science at all levels—from K-12 students through faculty ranks—in order to widen the STEM pathway that will welcome future scientists to this effort.
IRG-1: Spin-Orbit Coupling in Correlated Materials: Novel Phases and Phenomena
IRG-1 is creating novel materials designed to tune the delicate interplay between electron correlations arising from Coulomb interactions and spin-orbit interactions that are enhanced in heavier elements. Their focus is on 5d materials where tuning by chemistry, structure and epitaxial strain enables topological phases, quantum phase transitions and novel magnetism.
IRG-2: Control of 2D Electronic Structure and 1D Interfaces by Surface Functionalization of Group IV Graphane Analogues
IRG-2 is creating new materials: single atom thick 2D materials reminiscent of graphene but composed of heavier group IV atoms. These allow tuning of electronic properties by covalently attaching surface species to enable novel electronic phases and spin physics. Spatially-patterning in 2D creates the exciting possibility of novel 1D interfaces.
IRG-3: Nonlinear Interactions Between Spin Flux and Engineered Magnetic Textures
IRG-3 is pushing spin transport studies into the nonlinear regime with a program that aims to understand spin fluxes interacting with magnetic textures. Nonlinear response could move beyond diffusive spin currents to enable novel approaches to spin manipulation and control for next generation spintronics.
CEM’s aggressive Seed Funding program complements the research performed within the IRGs by providing an agile mechanism that supports the emerging developments in materials research, and identifies and nurtures future leaders. This extends the impact of the CEM beyond the membership of the IRGs. CEM is a founding member of the OSU Materials Research Seed Grant Program. This integrated program, started in 2010, jointly leverages resources of three organizations to achieve the greatest impact for seeding excellence in materials research of varying scopes.
