Self-organized nanostripes are observed in various light-rare-earth (LRE)-based 123-type high-Tc superconductors in the as-grown state by means of AFM and STM topography measurements. These observations indicate that the nanostripes are formed during the crystal growth process. The necessary oxygenation step to obtain superconducting samples causes the formation of twin boundaries and thus, deforms the original arrangement of the nanostripes.
