• change rapidly by several angströms due to the sudden release of stress. Furthermore, a Helmholtz double layer builds on the surface of a metal immersed in an electrolyte or a polar solvent, forming a capacitor [23]. When changing the bias this layer may become instable and thus influence the I–Vs. Its

This is corroborated by the fact that signals like in Figure 2a can also be obtained when there is no direct ohmic contact between the two electrodes, meaning that any charge transport between the working

Conclusion The results show that the temperature dependence of the Helmholtz double layer is the main reason for the light-induced signal of a GCQS under laser illumination. In contrast, for the electrochemically closed, but dried contacts the thermovoltage due to a two
