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.
