Extended Data Fig. 1. Spontaneous formation of MiGs nanostructure by thermal annealing of metallic Mg on GaN.

Extended Data Fig. 1

a, Step-1: Deposition of metallic Mg film on (0001) GaN. b, Step-2: The intercalation behaviour of Mg sheets into GaN at elevated temperature. c, Step-3: Post-cooling, and removal of acid-soluble residues, associated with the random exfoliation of MiGs nanofilms. The STEM observations of the MiGs phases and discussions are in Extended Data Fig. 5 and Supplementary Note 3.
