In this thesis we address cryogenic nano-electro-mechanical systems (NEMS) from 30 mK to 30 K sensitive to conditions involving fluctuations or disorder. The fundamental aspects studied are ubiquitous in NEMS physics, and for some of them go beyond, with possible analogies with phase transitions or NMR.In the first part of this work we focus on the NEMS position noise, which is a good example of Brownian motion within a confinement potential. Owing to the system’s intrinsic geometric nonlinearity, the potential anharmonicity translates each mode’s Brownian motion into fluctuations of the structure’s resonance eigenfrequencies. As a result we observe experimentally a spectral diffusion phenomenon that manifests through a linewidth broadening...
