Misfit Strain in Superlattices Controlling the Electron-Lattice Interaction via Microstrain in Active Layers
Figure 5
The microstrain ε (proportional to the Fe–Fe distance) and the misfit strain = 2 are plotted as a function of the doping for the “122” family and for the “1111” family of high-temperature superconducting FeAs compounds. The highlighted area is the region where the maximum occurs.
