In article number 1804433 , Olga Kraynis, Igor Lubomirsky, and co‐workers evaluate Raman spectroscopy as a characterization tool for anisotropic strain in lanthanide‐doped ceria films. The effective Grüneisen parameter, obtained by comparing substrate‐supported vs. self‐supported membranes, turns out to be 30% lower than its equivalent for bulk material. This suggests defect‐related properties play a major role when characterizing the strain of ceria‐based devices.
