Research Interest

My research programs are centered on using new materials and materials engineering approaches towards the formation of functional nanostructures with energy and electronic applications. Our research activities include:

  1. Energy devices: we focus on 1D oxide nanowires, 2D hydroxides nanosheets and reduced graphene oxides for electrochemical supercapacitors. We also develop high energy density capacitors with high pulse power, piezoelectrics energy harvestors and energy saving smart glass.

  2. Nanoelectronic materials: silicide formation, novel dielectrics, nanocrystals, nanowires, and nanocelullose hybrids. The functional devices that are being studied include touch panels, nanowire transistors, resistive switching memory, pressure sensors, gas sensors, and light emitting devices.

  3. Organic electronics: ferroelectric polymer, self assembled monolayers, polyelectrolyte and electrochromic materials. These materials have been applied for flexible organic memories, sensors, electrochromic and stretchable devices.

The approach we take is multidisciplinary, which involves materials science and engineering, physics, chemistry and electrical engineering. We study the fundamental charge transport, electrochemical properties, materials and device performance for practical interest in nano-scale devices for electronics, energy, sensors, flexible plastic circuits, stretchable and deformable devices, energy storage or harvesting.
