    Nanoporous GaN films are prepared by UV assisted electrochemical etching using HF solution as an electrolyte. To assess the optical quality and morphology of these nanoporous films, micro-photoluminescence (PL), micro-Raman ...
  • Fu, X.L.; Li, Yi; Schuh, C.A. (2007-01)
    The homogeneous deformation of Zr-based bulk metallic glass composites is studied near the glass transition temperature, at various levels of reinforcement volume fraction. Through examination of the constitutive response, ...
  • Fu, X.L.; Li, Yi; Schuh, C.A. (2006-01)
    Macroscopic ductility is promoted in bulk metallic glasses by both composite reinforcements (at low temperatures) and by the activation of viscous flow mechanisms (at high temperatures). It is of fundamental interest to ...
  • Chang, Choon Wai; Choi, Z.-S.; Thompson, Carl V.; Gan, C.L.; Pey, Kin Leong; Choi, Wee Kiong; Hwang, N. (2005-01)
    Three terminal ‘dotted-I’ interconnect structures, with vias at both ends and an additional via in the middle, were tested under various test conditions. Mortalities (failures) were found in right segments with jL value ...
