Thermal transport in one-dimensional micro/nanoscale structures

  • Developed experiment for thermal characterization of one-dimensional nanostructure and the secondary porosity. Other effects that generated from the sample preparation and their impacts on the measurement are also analyzed.
  • Designed experiment setup to fabricate ultra-thin organic and inorganic films that are utilized in microelectronic devices. Measure the lateral and vertical thermophysical properties and performance by various techniques including transient electrothermal, laser flash and photothermal technique
  • Employed molecular dynamics (MD) simulation to research the effects of heat fluence in near-field surface nanostructuring procedure and induced nanoscale shock wave phenomena during the laser-material interaction
  • Studied the influence of temperature and pressure on deposition of carbon atoms on silicon substrate and consequent fraction of sp3 bonds in the deposited structure utilizing high-performance computer to assist parallel MD simulation
