Large Polaron Conduction, Photoconductivity, and Photochromism in GdO_xH_3−2x Oxyhydride Thin Films

At ambient conditions, rare-earth oxyhydride thin films show reversible photochromism and photoconductivity, while their mechanism and relation are still unclear. In this work, this question is explored with in situ time-resolved measurements of both optical and transport properties of Gd-based oxyhydride thin films. It is found that p-type...
