Superstructure in bismuth rich substituted bismuth oxides
A study of superlattice ordering in substituted bismuth oxides is proposed. Bismuth rich compositions at the 14:1 B:M (where M = W/La and Ta) ratio will be investigated. These... -
High-Temperature Neutron Diffraction of Thermoelectric Materials
We wish to investigate the origin of the promising thermoelectic performance of oxy-chalcogenides BiOCuQ (Q = S, Se, Te) and related phases. We wish to explore whether the low... -
Pressure and Temperature-Induced Phase Transformations in PbZrO3-BiFeO3 Ceramics
The proposed experiment involves identification of the phase boundaries and determination of the crystal structures of PbZrO3-BiFeO3 (PZ-BF) ceramics as a function of... -
Magnetoelectric coupling in the multiferroic ceramic BiFeO3 - PbTiO3
The polycrystalline ceramic BiFeO3 - PbTiO3 is both ferroelectric and antiferromagnetic for a wide range of compositional space. We have shown in previous experiments that (1)... -
Probing Novel Phenomena in Sodium Bismuth Titanate
Sodium Bismuth Titanate, Na0.5Bi0.5TiO3 (NBT) is a mixed A-site perovskite. It is both of commercial interest, due to its usage in lead-free piezoelectric solid-solutions; and...
