It was a sample of SrTiO3 epitaxial membrane stamped on a Nb doped SrTiO3 substrate. The chunk was prepared using Nvision then the whole sample underwent a thermal treatment under atmospheric pressure. The thermal treatment has completely recrystallised the sample with the implemented Ga to form different forms of oxides. These new grains formed an image of doves in the sample after thinning down.
