Advanced Materials Technologies, EarlyView.Polycrystalline diamond (PCD) is directly bonded to 3C‐SiC for GaN HEMTs on a 2‐inch wafer using an advanced room‐temperature process. Despite high thermal conductivity at the growth surface, phonon scattering at the fine‐grained nucleation side raises thermal resistance.

MATHEMATICAL EVOLUTION IN DISCRETE NETWORKS
MATHEMATICS FOR APPLICATIONS, 2014 This paper provides a mathematical explanation for the phenomenon of \triadic closure" so often seen in social networks. It appears to be a natural con- sequence when network change is constrained to be continuous. The concept of chordless cycles in the network's \irreducible spine" is used in the analysis of the network's dynamic behavior.
