Signatures of a Pressure-Induced Topological Quantum Phase Transition in BiTeI
Xiaoxiang Xi, Chunli Ma, Zhenxian Liu +6
We report the observation of two signatures of a pressure-induced topological quantum phase transition in the polar semiconductor BiTeI using x-ray powder diffraction and infrared…
Far-Infrared Conductivity Measurements of Pair Breaking in Superconducting NbTiN Thin Films Induced by an External Magnetic Field
Xiaoxiang Xi, J. Hwang, C. Martin +2
We report the complex optical conductivity of a superconducting thin-film of NbTiN in an external magnetic field. The field was applied parallel to the film surface…
The unusual thickness dependence of superconductivity in -MoGe thin films
H. Tashiro, J. M. Graybeal, D. B. Tanner +3
Thin films of -MoGe show progressively reduced 's as the thickness is decreased below 30 nm and the sheet resistance exceeds 100 . We have performed far-infrared…
Phonon anomaly at the charge ordering transition in 1T-TaS2
L. V. Gasparov, K. G. Brown, A. C. Wint +5
The infrared reflectance of the transition metal chalcogenide 1T-TaS2 has been measured at temperatures from 30K to 360K over 30-45,000cm^-1 (4meV-5.5eV). The optical conductivity…
