• Joule dissipation leads to energy dissipation of the cantilever oscillation and a reduction in amplitude for constant excitation. They focus on two-dimensional materials and discuss how the reduction in amplitude resulting from energy dissipation influences the height measurement. In addition to the

• its voltage dependence, it is reasonable to assume an electronic origin. Previously, it has been proposed in other systems that a plausible explanation to this effect is related to Joule dissipation [80][81]. The physical processes that lead to Joule dissipation are as follows: (i) In the presence of

• an effective tip–sample voltage, the oscillating AFM tip generates a time-dependent electrical field, which induces a current and Joule dissipation due to the non-zero resistance of the material. These currents induce an oscillating charge movement. (ii) Simultaneously, these moving charges also

• suppressed. It allows us to use normal-state heat conductivity both in the SN and the S region in the heat conductance equation for the calculation of δTe. This is in contrast to S-N-S and S’-S-S’ junctions where heat conductivity is suppressed in the superconducting banks. In our model Joule dissipation is

On increasing Vdc, the temperature of the constriction grows and the conductance starts to fluctuate. The general trend is that G(t) decreases when stepping up Vdc. We also consistently observe a

• length scale of only a few nanometres. At the same time, Joule dissipation affects devices as they are scaled down, and the increasing power densities require adequate thermal management to avoid performance degradation or failure [1]. Hot spots can appear due to increased local energy dissipation at
