    Compositionally Asymmetric Tri-Color Superlattices Grown by Pulsed Laser Deposition

    Compositionally asymmetric tri-color superlattices (TCS) with a combination of BaTiO3/SrTiO3/CaTiO3 have been grown by pulsed laser deposition (PLD) on atomically-flat SrRuO3-covered (001) SrTiO3 substrates. Cond...

    Effect of Ambient Gas Pressure on Pulsed Laser Ablation Plume Dynamics and ZnTe Film Growth

    Epitaxial thin films of nitrogen-doped p-ZnTe were grown on single-crystal, semi-insulating GaAs substrates via pulsed laser ablation of a stoichiometric ZnTe target. Both low pressure nitrogen ambients and hi...

    REAL-TIME in situ MONITORING OF DEFECT EVOLUTION AT WIDEGAP II-VI/GaAs HETEROINTERFACES DURING EPITAXIAL GROWTH

    We report the real-time in situ observation of heterointerface dislocation formation during the growth of lattice-mismatched widegap II-VI/GaAs heterostructures. Such observations were made by employing a near-no...
