# overview
The main focus area of the research in our laboratory is (i) chemical synthesis of nanoscale hetero-structures of semiconducting and magnetic materials and (ii) real-time laser spectroscopic investigation of the dynamic electronic and magnetic properties of the nanostructures prepared from (i). Ultimately, we would like to obtain fundamental understanding of how the dynamic optical, electronic and magnetic properties in structurally complex nanoscale materials can be controlled by tuning their chemical and structural parameters. The knowledge obtained from these researches lays fundamental background essential in many practical applications, such as designing nanoscale electronic devices and light energy-harvesting materials.
