Cubic (Al)GaN/AlN multiple quantum wells were grown by plasma assisted molecular beam epitaxy with three different configurations at interfaces. We employ temperature-dependent photoluminescence to characterize interface imperfections. Our results sh

Defects play a fundamental issue on physical properties of wide bandgap materials. We present here the effect of preparation and annealing conditions on the properties of Nb 2 O 5 synthesized by Pechini method. Structural characterization, Raman spec

In this paper, we report on structural and optical properties of terbium and europium doped barium stannate phosphors (BaSnO3) synthesised by conventional solid state reaction method. We have studied those materials by using X-ray diffraction (XRD),

In this work, we have investigated magneto-transport and polarization resolved photoluminescence of a GaAs/AlGaAs resonant tunneling diode with Si delta-doping at the center of the quantum well under a magnetic field parallel to the tunnel current. T
