Maps for the length of the scattering vector Q from the Ge QW layer in the vicinity of the qubits: (a) diffraction map for the 335 reflection; (b) diffraction map; (c) 33̅5 diffraction map. The direction of the lattice planes is described by the white arrows. The area on the sample which is covered by all three reflections and thus suitable for calculation of the full strain tensor is outlined by the red dashed box.
