N2 - The electron-glass dynamics of Anderson-localized GeSbTe films is dramatically slowed down following a brief infrared illumination that increases the system carrier concentration (and thus its conductance). These results demonstrate that the dynamics exhibited by electron glasses is more sensitive to carrier concentration than to disorder. In turn, this seems to imply that many-body effects such as the orthogonality catastrophe must play a role in the sluggish dynamics observed in the intrinsic electron glasses.
