Electronic Functions at Nano-scale Level Research Team
Team Leader
Yousoo KIM (D.Eng.)
The Nano-scale Electronic Functions Research Team aims at creating and controlling electronic functions of nano-scale materials. Concretely, the research is promoted centering on the enumerated three research topics as follows. (1) The measurement of the electron transport in a single molecule and the research on the function creation: It aims to discover the operation principle of molecular devices and to control them by use of the degree of freedom of the molecules. (2) The formation and the electronic function creation of the low-dimensional nanostructures: It aims at the creation of electronic functions of 1-D or 2-D atomic or molecular structures by use of self assembly or chain reactions. (3) The electronic function creation of the molecule related to the living body, such as model biomembrane, DNA and protein molecules. In this research team, it starts from a simple molecular system, and the electronic function creation and the research with a molecular system with more degree of freedom are developed.
