Morphological change from nano-cube to nano-sphere by addition of Ni to W in RF thermal plasma synthesis

Kim Y.M., Na H., Lee B.J., Lee W., Lee B.J., Lee W., Hwang N.M., Choi H., Korea Institute of Industrial Technology, KR

Pure W and W-Ni nano-particles were effectively synthesized by feeding thermo-physically favorable oxide feedstock micro-powder into argon-hydrogen thermal plasma. During the process, feedstock particle underwent a vaporization, reduction, and condensation pathway. Significant amount of nano-cube [...]

Thin film solar cell based on microcrystalline nanostructure silicon grown in low temperature condition

Chung Y.B., Lim J.S., Kim H., Kim J.K., Hwang N.M., Kim H., Kim J.K., Park Y.J., Seoul National University, KR

High quality microcrystalline silicon thin film grown by Hot-Wire Chemical Vapor Deposition(HWCVD) and subsequently manufactured solar cells are presented. Intrinsic layer photoconductivity data is provided for one of the film quality measures, and the result [...]

Molecular Dynamics Study on Deposition Behaviors of Au Nanocluster on Substrates of Different Orientation

Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee J-G, Lee K-R, Lee K.H., Lee S-C, Hwang N.M., Korea Institute of Science and Technology, KR

Effects of the substrate orientation on the homo-epitaxial rearrangement of the deposited Au cluster were studied by molecular dynamics (MD) simulation using embedded-atom method (EAM) potential. (011), (001), and (111) low indexed surfaces were used [...]
