In optical detection setups to measure the deflection of micro-cantilevers, part of the sensing light is absorbed, heating the mechanical probe. We present experimental evidences of a frequency shift of the resonant modes of a cantilever when the light power of the optical measurement set-up is increased. This frequency shift is a signature of the temperature rise, and presents a dependence on the mode number. An analytical model is derived to take into account the temperature profile along the…

Photoinduced force microscopy (PiFM) measures changes in the force between an atomically sharp tip and the sample under the influence of applied radiation. Several mechanisms contribute to the

Force microscopy cantilevers locally heated in a fluid: Temperature fields and effects on the dynamics

Atomic force microscopy cantilevers are often, intentionally or not, heated at their extremity. We describe a model to compute the resulting temperature field in the cantilever and in the surrounding

Thermal noise of a cryocooled silicon cantilever locally heated up to its melting point.

This experiment studies a microcantilever brought out of equilibrium by a strong heat flux generated by the absorption of the light of a laser, and demonstrates how the thermal fluctuations of all the observed degrees of freedom are much lower than what is expected from the average temperature of the system.

Accelerating the heat diffusion: fast thermal relaxation of a micro-cantilever

In most systems, thermal diffusion is intrinsically slow with respect to mechanical relaxation. We devise here a generic approach to accelerate the relaxation of the temperature field of a 1D object,
