RESEARCH AREA


Brief Introduction

Research areas of nanotectonics laboratory are the synthesis of nano-structured building-blocks, assembly of building-blocks into higher-order architectures, and electro-photo behaviors of nanomaterials. Based on these researches, we aim at the development of revolutionary architectures that can be utilized as tool kits for ET, BT, IT and NT. Target applications include fuel & solar cells, sensing & removal of hazardous materials, nanomedicine, optoelectronics, plasmonics, photovoltaics, and nanoelectronic devices.
