Research Overview

The unique properties of low dimensional systems are generally understood by considering enhanced quantum effects and increased correlations due to the reduction of available phase space. The focus of Kim group research is the mesoscopic investigation of transport phenomena, particularly, electric, thermal and thermoelectrical properties of low dimensional nanoscale materials. These materials include carbon nanotubes, organic and inorganic nanowires, 2-dimensional mesoscopic single crystals, and single organic molecules. The use of modern state-of-the-art semiconductor device fabrication techniques and the development of new methods of material synthesis/manipulation are essential parts of this research. We have initiated these efforts at Columbia University, and will continue to make innovations in microscopic experimental tools and methods, and to investigate the electric, thermal/thermoelectric transport properties of the nanoscale materials. Specifically, our research focuses are:

  • Quantum charge and thermal transport phenomena in 1-dimensional nanoscaled materials such as carbon nanotubes and semiconducting/ metallic nanowires
  • Mesoscopic thermoelectricity and thermoelectric applications of nanoscaled materials in the quantum transport regime.
  • Transport phenomena in novel 2-dimensional atomic crystals including graphene and other layered systems.
  • Application of mesoscopic electron transport and thermodynamic processes for electronic devices, sensors and biological manipulation/detection systems.
