EE-Electrophysics Seminar

Speaker: Faxian Xiu, Electrical Engineering Department at UCLA

Talk Title: Magnetic Nanomaterials and Nanodevices - Emerging Strategies for Beating Moore’s Law

Abstract: Magnetic nanomaterials have potentials for developing new-generation electric devices to resolve power consumptions and variability issues in today’s microelectronics industry. In this talk, I will present my recent research on the development of high-Curie-temperature Mn0.05Ge0.95 quantum dots with a ferromagnetic order above room temperature. I will describe an approach to probe the electric-field control of ferromagnetism in this material and demonstrate the operation temperature up to 300 K. I will also briefly discuss some of recent advance in voltage-controlled surface states in topological insulator Bi2Te3 nanoribbons. The surface states of the topological nanoribbon can be significantly enhanced up to 51 % by applying an external gate voltage. These novel magnetic and electronic materials could be potentially used for the long-sought power dissipationless applications.

Biography: Dr. Faxian Xiu is currently a staff research associate with the Electrical Engineering department at UCLA. He is associated with two research centers in California: the Functional Engineered Nano Architectonics Center and the Western Institute of Nanoelectronics. He received his Masters degree in Materials Science and Engineering from the same university in 2002, and his Ph. D. degree from the Electrical Engineering at UC Riverside in 2007. After his Ph.D., he worked for ZN technology Incorporation for two years before he joined UCLA as a staff research associate.
Dr. Xiu has interdisciplinary background involving both materials science and electrical engineering. He has over 40 peer-reviewed publications and received numerous media attention on his work of dilute magnetic semiconductors. His current research interest includes spintronic and nanoelectronic devices based on the Mn-doped Ge quantum dots and topological insulator nanoribbons.
