Dataset Figures paper entitled "Grain Boundaries and the Photoresponse of Epitaxial LaFeO3 films"

Dataset Description: Grain Boundaries and the Photoresponse of Epitaxial LaFeO3 films The dataset associated with the study ""Grain Boundaries and the Photoresponse of Epitaxial LaFeO3 films"" show that grain boundary engineering in narrow band-gap oxide thin films is a suited strategy to enhance their photoresponse. Motivation Centrosymmetric LaFeO3 (LFO) shows photovoltaic effect when sandwiched between asymmetric electrodes, which stems from the built-in potential induced by the different work functions of the top and bottom electrodes, interfacial polar discontinuity or even flexoelectric fields. However, the complex microstructure of epitaxial LFO film contributes to its photoresponse differently depending on the crystallographic domain landscape and the nature of the grain boundaries originating between them. Dataset Content and Structure The dataset includes the following categories of data: Photoresponse measurements – J/V curves. High resolution HAADF-STEM images. 4D-STEM for the study of the cristallographic domains within the thin films. EELS measurements. AFM images. XRD measurements - Reciprocal Space Maps.
