Junlei Zhao

I am a postdoctoral researcher at the Accelerator Laboratory, Department of Physics, University of Helsinki. My research activities have focused on multi-scaled computational simulations of nanomaterials, including the growth of nanoparticles in the gas phase, the surface and interface evolution of metallic alloys and irradiation effects on the physical properties of solids. From 2014, I studied the phase transition of Si clusters using molecular dynamics. Later, I applied Metropolis Monte Carlo method to study the phase segregation of NiCr clusters. In 2016, I use MD and KMC methods together with an analytical model to successfully explain the formation of Fe nanocubes in a magnetron sputtering cluster source. I also studied the thermal oxidation mechanism of Pd nanoparticles supported on CuO nanowires with DFT calculations. Most recently, I investigated the formation and emission mechanism of the metallic nanoparticles in a matrix assembly cluster source (MACS) using MD simulations. Currently, I am also interested in the formation of bi- and tri- metallic nanoalloys in MACS and inert gas phase condensation as well as the application of machine learning algorithms in materials science.
