Sabar Hutagalung
Dr. Sabar D. Hutagalung received a Drs degree (Applied Physics) from University of North Sumatra (USU), Medan, Indonesia in 1989 and a Ph.D. degree (Materials Science) from University of Technology Malaysia (UTM), Johor Bahru, Malaysia, in 1997. He was a lecturer at the USU from 1991 to 1999. From 1999 to 2003, he was with the Faculty of Engineering, Legenda College, Malaysia as a lecturer, a head of department and later he served as a dean of faculty. Since December 2003 he has been with the School of Materials and Mineral Resources Engineering, University of Science Malaysia (USM), Penang, Malaysia. His research interests are nanomaterials, nanoelectronics and electro-active ceramic materials areas, especially synthesis and characterization of semiconductor nanostructured materials (nanowires, nanorods, nanoparticles and quantum dots), development of silicon nanowire transistor by AFM lithography, investigation of high-K dielectric and giant magnetoresistance ceramic materials, and development of ceramic-based EMI shielding materials.
