"Combinatorial approach to materials discovery "

Professor I. Takeuchi , University of Maryland
[Host: Joseph Poon and Ian Harrison]
Throughout the history of mankind, scientists and engineers have relied on the slow and random trial-and-error process for materials discovery. The combinatorial approach to materials is an emerging new method of materials research aimed at drastically increasing the rate and efficiency at which new materials are discovered and improved. In order to rapidly survey a large compositional landscape, up to thousands of compositionally varying samples are synthesized, processed, and screened in a single experiment. We have developed thin film combinatorial techniques for exploring new materials phases in a number of key technology areas including electronic, magnetic, and smart materials. Our synthesis tools include combinatorial pulsed laser deposition systems and a UHV combinatorial co-sputtering system. Our rapid characterization tools include scanning SQUID microscopes for mapping properties of magnetic materials libraries and scanning near field microwave microscopes for screening dielectric and conducting materials. Recent developments in investigation of ferromagnetic shape memory alloys and ferroelectric materials will be discussed.
