Thermal behaviors of intrinsic defect clusters (self-interstitials and vacancies) in silicon crystals implanted with several metals including Cu were observed by photoluminescence measurements to investigate the influences of the metals on the diffusion of the intrinsic defects. Enhanced annihilations (EAs) of the defect clusters were observed only for an oxygen-lean floating zone (FZ) crystal implanted with Cu and annealed at temperatures between 400 °C and 600 °C, while they were not observed for any types of crystals (n- and p-type FZ and Czochralski crystals) implanted with Fe and Cr. The EAs of the defect clusters were well explained by a vehicle action of fast diffusing Cu for vacancy transportation.

    We performed a study on the probable existence of long-lived charged sleptons in the so-called coannihilation region of parameter space in the framework of the MSSM with supergravity-inspired soft SUSY breaking. We show the possibility to get long-lived charged sleptons in a tiny thin band of...

    An unparticle ${\mathcal {U}}$ with scaling dimension $d_{{\mathcal {U}}}$ has peculiar thermal properties due to its unique phase space structure. We find that the equation of state parameter $\omega_{{\mathcal {U}}}$ , the ratio of pressure to energy density, is given by $1/(2d_{{\mathcal...
