Thin films of nanostructures and low-dimensional materials are key ingredients of many devices including energy conversion devices including light emitting diodes, solar cells, batteries, water splitting cells, electronics including transistors and memories, chemical sensors including e-nose and e-tongue, and nanophotonics. Our research is focused on the design, control, and optimization of the nanostructures of inorganic/organic materials, such as metal oxides, 2D materials, and halide perovskites, to substantially improve the performance of the devices based on multiple thin films of nanostructures and low-dimensional materials.

Using nanotree structure photoelectrode, solar water splitting can efficiently produce hydrogen. To develop this field, it is necessary to cultivate human resources with complex knowledge in chemical processes, biology, and physics.
