(a) The β-Li2IrO3 crystal (orange) was glued onto an STO substrate (light blue) using epoxy glue (teal), mounted on a pre-tilted sample holder and aligned with the surface parallel to the Ga+ ion beam. An e− beam was subsequently used to remove Ga implantations. Side view of the (b) unprocessed sample and (c) thinned sample along the ion beam (indicated by the direction of the red arrow in (a), which is also shown in red in (b) and (c) perpendicular to the picture plane). |
