Fig. 4: Evolution of lattice spacing during a single heating cycle.

Clockwise, local mappings of the dCu 111 are shown from heating to cooling (a). The average dCu 111, obtained from axial strain scans, is displayed for different temperatures (b), with the theoretical values being calculated under the assumption of linear elastic thermal expansion. The color scale bar of the local mappings is shown in the y-axis of (b). After the single heating cycle, the lattice spacing indicates the formation of 1st-order tensile strain.
