Unusual Low-Energy Phonon Dynamics in the Negative Thermal Expansion Compound ZrW2O8
Jason N. Hancock, Chandra Turpen, Zack Schlesinger +2
An infrared study of the phonon spectra of ZrW2O8 as a function of temperature which includes the low energy (2-10 meV) region relevant to negative thermal expansion is reported an…
Low temperature field-effect in crystalline organic material
V. Y. Butko, J. C. Lashley, A. P. Ramirez
Molecular organic materials offer the promise of novel electronic devices but also present challenges for understanding charge transport in narrow band systems. Low temperature stu…
Valence-electron transfer and a metal-insulator transition in a strongly correlated perovskite oxide
A. P. Ramirez, G. Lawes, D. Li +1
We present transport and thermal data for the quadruple-perovskites MCu3(Ti1-xRux)4O12 where 0 < x < 1. A metal-insulator transition (MIT) occurs for Ru concentrations x~0.75. At t…
