pi-bonds in graphene and surface of topological insulator Bi2Se3
G. J. Shu, S. C. Liou, F. C. Chou
Chemical bond analysis for the topological insulator (TI) Bi2Se3 following valence bond theory and VSEPR rule is proposed and compared to that of graphene. The existence of pi-bond…
PbCu3TeO7: An S=1/2 staircase Kagome lattice with significant intra- and inter-plane couplings
B. Koteswararao, R. Kumar, Jayita Chakraborty +5
We have synthesized polycrystalline and single crystal samples of PbCu3TeO7 and studied its properties via magnetic susceptibility chi(T) and heat-capacity Cp(T) measurements and a…
Anomalous behavior in the phonon dispersion of the (001) surface of BiTe determined from helium atom-surface scattering measurements
Colin Howard, M. El-Batanouny, R. Sankar +1
We employ inelastic helium atom-surface scattering to measure the low energy phonon dispersion along high-symmetry directions on the surface of the topological insulator BiTe$_…
Evidence for Dimer Crystal Melting in the Frustrated Spin-Ladder BiCu2PO6
K. -Y. Choi, J. W. Hwang, P. Lemmens +3
In the spin ladder compound BiCuPO there exists a decisive dynamics of spin excitations that we classify and characterize using inelastic light scattering. We observe low-e…
Plasmons dispersion and nonvertical interband transitions in single-crystal Bi2Se3 investigated by electron energy loss spectroscopy
S. C. Liou, M. -W. Chu, R. Sankar +4
Plasmons dispersion and nonvertical interband transitions in Bi2Se3 single crystals were investigated by electron energy-loss spectroscopy in conjunction with (scanning) transmissi…
