Copper nanotubes (NTs) and nanowires (NWs) with Y‐ and step‐shaped topologies (see image) are built via electrodeposition inside anodic aluminum oxide templates. Thermal‐expansion measurements demonstrate that their thermal‐expansion coefficients (TECs) are temperature dependent and that the TECs of the stem/large‐diameter segments are more sensitive than those of the branch/small‐diameter segments.
