A planar film of gadolinia-doped ceria (GDC) was deposited on the (100) surface of an yttria stabilized zirconia (YSZ) single crystal substrate. Upon annealing, the film breaks up into an array of nanoislands (see figure) due to stress driven instability, providing an inexpensive route to the formation of ordered nanoarrays.
