    DC conduction behavior of Bi3.15Nd0.85Ti3O12 thin films grown by RF-magnetron sputtering

    The Bi3.15Nd0.85Ti3O12 (BNT) thin films were deposited on Pt(111)/Ti/SiO2/Si substrates by using RF-magnetron sputtering method and studied the ferroelectric and leakage current charateristics. The polarization –...

    Photoluminescence of strain-induced coupled InGaAs/GaAs quantum-dot pairs

    Coupled quantum dot-pairs were fabricated by growing InP self-assembled islands as stressors on InGaAs/GaAs double quantum wells. State filling in the photoluminescence spectra was used to resolve the quantum ...
