a, Initial color map of \({\rm{d\it V}}/{\rm{d\it I}}\) as a function of \({I}_{{d.c.}}\) and \({B}_{z}\). Note that the patterns in this figure and in Fig. 1f exhibit variations, as the measurements were conducted on different thermal cycling batches used for comparison. b, Color map of \({\rm{d\it V}}/{\rm{d\it I}}\) as a function of \({I}_{{\rm{d.c.}}}\) and \({B}_{{\rm{z}}}\) obtained after thermal cycling by using a local heater integrated near Device 1. This corresponds to a thermal modulation of 17.8 K (see Supplemental Note 2 for details), which is well below the nematic transition temperature Tnem ≈ 30 K. The oscillation periods of both \({I}_{{\rm{c}}}^{{\prime} }\) (green arrow) and \({I}_{{\rm{c}}}^{{\prime} {\prime} }\) (purple arrow) are changed after thermal cycling, indicating a clear thermal modulation.
