  • Patent number: 7498082
    Abstract: A dielectric ceramic composition including dielectric particles comprising a main ingredient phase having barium titanate as its main ingredient and a diffusion phase present at the periphery of said main ingredient phase, wherein when an average value of the depth where sub ingredient elements present at said diffusion phase diffuses from a surface of said diffusion phase toward a center of said dielectric particle is designated as an average diffusion depth, a dispersion of the average diffusion depth among the dielectric particles is, in terms of CV value, 5 to 30%. According to the present invention, an electronic device excellent in all of the dielectric constant, high temperature accelerated life, TC bias, and IR temperature dependency can be provided.

  • Patent number: 7482059
    Abstract: A semiconductor nanocrystal complex including a metal layer formed on the outer surface of a semiconductor nanocrystal core after synthesis of the semiconductor nanocrystal core and a method for preparing a nanocrystal complex comprising forming a metal layer on a semiconductor nanocrystal core after synthesis of the semiconductor nanocrystal core. The metal layer may passivate the surface of the semiconductor nanocrystal core and protect the semiconductor nanocrystal core from the effects of oxidation. Also provided is a semiconductor nanocrystal complex with a shell grown onto the metal layer formed on the semiconductor nanocrystal core. In this embodiment, the metal layer may prevent lattice mismatch between the semiconductor shell and the semiconductor nanocrystal core.
