Electronic structure of Ba-Ga-Ge-Si Type I Clathrates: A Ge and Ga K-Edge Study

November 9, 2012
Author(s)
Winnie Wong-Ng, Azzam Mansour, Joshua Martin, George S. Nolas
XANES spectroscopy was successfully used to study changes in the density of unoccupied states for silicon substituted Ba8Ga16Ge30-xSix type I clathrates. Partial density of unoccupied states with p character is modified for both Ga and Ge upon Si

Four-color laser white illuminant demonstrating high color-rendering quality
