His group explores the vapor- and solution-based synthesis and physical properties of novel materials, particularly transition-metal oxides and hybrid halide perovskites, in the forms of thin films, nanomaterials and mixed-dimensional nanocomposites. His research targets at diverse optoelectronic, data storage and energy related devices including field effect transistors, nonvolatile memories, solar cells and photodetectors. The aim is to find disruptive materials-based solutions via composition-structure-energy-interface engineering to address resource and technology challenges. Tom’s group has witnessed the career development of more than 20 PhD students and 30 postdocs who now hold academic and industry positions in countries including China, India, Singapore, UK, Japan, Korea, France, and US. He also serves as Associate Editor for ACS Applied Materials & Interfaces.
