Claims

C1strongest claim

Heating inherently generates mechanical stress through thermal expansion, which in turn produces measurable electrical signals via electromechanical coupling; the on-chip device probes the anisotropy of the piezoelectric tensor through the thermally generated current, exhibiting twofold and threefold responses for X-cut and Z-cut crystals respectively.

C2weakest assumption

The observed electrical signals arise primarily from piezoelectric response to thermally generated stress rather than from direct thermoelectric, pyroelectric, or contact-related effects, and that the device geometry isolates the thermomechanical contribution without significant artifacts.

C3one line summary

Heating quartz on-chip produces anisotropic electrical currents from thermally induced stress via piezoelectric coupling, showing twofold symmetry in X-cut and threefold in Z-cut crystals, detectable in both current and voltage modes.
