We propose to investigate the structure of the new ¿ordered¿ phases within the Bi2Se3-Bi2Te3 phase diagram of the newly discovered Topological Insulators. The bulk properties of... -
Diffuse scattering in the paraelectric phase of titanite
Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short... -
Influence of superstructures on rich transport properties of lithium cobaltate
In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the... -
