Research Interests and achievement
Updated on September 3, 2006
My research has primarily been exploring the frontier of physics in novel materials by advanced thin film preparation techniques. During my tenure in Bell Lab Physical Research over a span of 22 years, the earlier representative work was magnetic superlattices by the invention of metal molecular beam epitaxy in 1981-86. The pioneer work on synthetic rare earth magnetic superlattices demonstrated for the first time the modulation effect of magnetic properties by artificial layering, and invented the notion of "magnetronics”. During 1987-92, high temperature superconducting perovskite oxide films was the main focus by inventing oxide molecular beam epitaxy, and this has led to studies of anisotropic superconducting properties in layered cooperates, and understanding of the fundamental HTSC mechanism. From 1993 till now, my interest has shifted toward high dielectric constant (κ) oxides for nano electronic and photonic applications. Two new transparent conducting oxides were discovered for modern display and electro-optical devices. During last decade major efforts were devoted to high κ dieletric film synthesis for DRAMs, wireless communication, and recently gate oxide applications. The discovery of a mixed oxide for compond semiconductors passivation demonstrated for the first time the long sought GaAs-based MOSFETs, now considered as a viable technology replacing Si CMOS in near future. Another new program being developed is the spintronics research to study dilutely doped magnetic oxides based on high κ dielectrics, spin polarization anaylsis by Andreev Reflection, and spin injection and dynamics in Datta-Das Spin FET made of half metals and compound semiconductors
