Supporting data for the article titled "Encapsulation of methylammonium lead bromide perovskite in nanoporous GaN". The article was accepted for publication in 2019 in the journal "APL Materials". Supplementary material is available from the publisher (AIP). The data files provided are named according to the specific figures in the article in which they are used. Data for Figure 3: Scanning transmission electron microscopy and energy dispersive X-ray spectroscopy (STEM-EDX) data (.ser) and metadata (.emi), as well as elemental maps of the spatial distribution of Ga, Pb, Br in a perovskite/porous GaN composite (2D arrays of the peak intensity of the respective K-alpha lines extracted from the EDX spectra at each point, in CSV format). Data for Figures 4 and 5: Photoluminescence (PL) emission spectra of perovskite samples presented in a two-column CSV format with one header row. Data for Figure S1: EDX spectra of a perovskite/porous GaN composite measured on a pore and between pores, presented in a two-column CSV format with one header row.
