“…K. Sudheendran et al [12] The microstructure of the synthesized compound exhibiting elongated dispersed grains is depicted in Figure 1 As proposed by J C Nino et al [13], Cu 2+ cannot establish a distorted coordination, which is required for the stabilization of the monoclinic structure. Energy dispersive spectral (EDS) pattern (Figure 1(b) and 2(b)) at two different region was also obtained for elemental analysis and individual element in wt% at two different regions is specified in Table 2.…”

Abstract:Copper doped bismuth vanadate with nominal composition Bi 1.5 CuV 1.5 O 7 was synthesized using classical solid state reaction method. X-ray analysis conform the formation of monoclinic phase in the as-prepared compound. Different grain size after primary investigation reveals the influence of dopant ions on the domain structure and its microstructure. The phase compositions behaviour was found to be strongly correlated with the partial substitution of heterovalent cation dopant. Energy dispersive spectra confirm the occurrence of stoichiometric elements within the synthesized compounds.

a b s t r a c tWe have investigated optical and band alignment properties of pulsed laser deposited amorphous thin films of bismuth based monoclinic pyrochlore Bi 2 Zn 2/3Àx/3 Nb 4/3À2x/3 Zr x O 7 (Zr-BZN) where x = 0.4 on quartz and silicon substrates, respectively. The optical parameters, such as complex refractive index (n À jk), energy bandgap (E g ), complex dielectric function (e 0 À je 00 ), and complex conductivity (r 0 À jr 00 ) and associated dispersion parameters were estimated from the UV-Visible transmission spectra. The analysis of refractive index dispersion confirmed the Wemple-DiDomenico single-effective-oscillator model for the direct inter-band transition. The valence band of Zr-BZN is found to be $0.1 eV above that of silicon. The numerical values for conduction band offset DE C on silicon and optical bandgap E g were estimated to be $2.46 eV and $3.46 eV, respectively for Zr-BZN samples. We determined a complete electron band offset dominated type II staggered band lineup of this high-k dielectric/semiconductor heterostructure, where a straight forward spatial confinement of electrons and holes is facilitated. These important results can play critical role and provide key insight for the practical applications of Zr-BZN material, especially in CMOS (complementary metal-oxide-semiconductor) logic and memory devices.
