The First Principle Group based at National ChengKung University, Taiwan, is using molecular dynamics simulation to find out more about the thermal characteristics of carbon nanotubes. To exact the heat flux input and to control the temperature, a thermal reservoir according to canonical ensemble has been devised. The quantum effect defining the precise temperature from the absolute zero Kelvin and above is included by applying phonon statistics to the specific heat.
The scaling law of thermal conductivity as a function of temperature and length is inferred from the simulation results, which allows the researchers to characterize CNTs with tube lengths that go beyond the limits of molecular dynamics.
The researchers presented their work in Nanotechnology.
The research team is the First Principle Group working on nanoscience and plasma physics from the first principles. Michael Wu has just finished his undergraduate study and plans to continue his higher education abroad after serving in the military. James J Y Hsu has just published his book Nanocomputing – Computational Physics for Nanoscience and Nanotechnology. He is professor of physics and the director of the Institute of Space, Astrophysical and Plasma Sciences at National ChengKung University. He is helping to organize the Conference on Computational Physics 2009, which will be held in Kaohsiung, Taiwan, and welcomes computational scientists to attend.
