infrared optics study of FeCrAs published today

Optical properties and electronic structure of nonmetal FeCrAs, published today in Physical Review B

The result of our collaboration with the laboratory of Christopher Homes, at Brookhaven National Laboratory, was published to day in Physical Review B (A. Akrap et al., Phys Rev B 89 (2014) 125115).  The samples for this research were grown by Wenlong Wu, and the measurements were done by Chris, Anna and Yaomin.  A central conclusion of this work is that the nonmetallic resistivity of FeCrAs is due to an anomalous scattering rate that increases with decreasing temperature, as opposed to loss of carriers.
