Transition metal oxides cover a wide spectrum of material categories, ranging from insulators and semiconductors to metal and superconductors; they exhibit a variety of properties, such as superconductivity, ferroelectricity, magnetism, colossal magnetoresistance, and multiferroicity. These properties have been exploited and tuned in epitaxial thin films structures, taking advantage of the structural sensitivity of the transition metal oxides and the rich electronic structures at the interface between structurally compatible materials. Our group's interests are in the complex oxide thin films that are ferroelectric and/or ferromagnetic. See research highlight here.
Organic semiconductors have distinctive advantages over inorganics in terms of flexibility, scalability, and sustainability. The potential of organic semiconductors to become viable material alternatives to the inorganic counterparts hinges on the availability of strategies to fabricate thin films with defined structure and morphology on a large scale. Our interests are in preparing organic thin films with desired morphology and exploit their electric and magnetic properties. See research highlight here.
Permanent magnet is critical for energy and information storage and conversion. The quest for high-performance permanent magnet with no rare or expensive elements is crucial for their future application. Our effort is to search and study novel permanent magnet aiming for high magnetic anisotropy and magnetization. See research highlight here.
