a, MIM image of device MW10. Here, the uncalibrated imaginary MIM signal is plotted for the purpose of identifying conducting features. Multiple conducting cracks are seen running from upper left to lower right. Inset: polar plot of the Raman peak P11 (210 cm−1) intensity, used to determine the crystal axes. b, Conductivity versus ng and T at 2 GHz deduced from MIM measurements in the centre of the white dotted square in a. c, Partial conductance parallel to the x axis (left) and y axis (right), measured in the white dotted square using the configurations shown in the insets.
