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.
