Welcome to DLC Research Group

Since 1991, our group has developed world-wide core competencies in the area of synthesis and application of diamond-like carbon (DLC) films. Using various deposition methods from plasma assisted CVD, ion beam deposition, ion plating to filtered vacuum arc process, we span almost whole spectrum of this material.

As the fundamental issues, we are playing with

  • Characterization of DLC Films : Structure and Properties
  • Modification of DLC Films by Third Element Addition or Nano-scale Structural Manipulation
  • Tribological Behavior of DLC Films : Environmental Dependence & Mechanism
  • Functionalization of DLC films for biological applications
  • Nanoscale structural manipulation of carbon films
  • Field Emission from Carbon Materials
  • Synthesis of Carbon Nanotube

For the applications, we are working on

  • Adhesion Improvement of DLC Films on Various Substrates From Polymer, Ceramic and Metals.
  • Design of Coating Layer for a Specific Application
  • Design and Implement of Production Scale Deposition Equipment
  • Development of Production Process
  • Stability of DLC coating in human body fluid environment

A number of our technologies were transferred to industry and successfully commercialized.

In 2000, our research was extended to computational materials simulation. This extension was triggered by our own needs to understand the atomic scale structural evolution of amorphous carbon films. However, our present research topics include

  • Electronic structure of novel diluted magnetic semiconducting materials (ab initio calculation)
  • Atomic scale interfacial mixing in nano-scale multilayer (classical MD)
  • Atomic structure and residual stress of tetrahedral amorphous carbon films (classical MD)
  • CNT growth mechanism : nitrogen effect (ab initio calculation)
  • Simulation of field emission from doped CNTs (ab initio calculation)
  • Interfacial phenomena of gate oxide layer in nanoscale CMOS devices (classical MD, an initio calc.)

We are pursuing a plan to develop the KIST suite for computational nanoscience (KIST-SCN) that is composed of

  • Massive molecular dynamics code with wide range of interatomic potentials
  • Kinetic MC
  • Active driven MD
  • Tight binding theory
  • ab intio calculation and MD/MC
  • Qunatum transport theory
  • Visualization and post analysis system.
