The nanomechanical properties of single-crystalline silicon cantilevers as resonating elements were investigated. It was observed that the flash heating the single-crystalline silicon cantilever at 1000°C in ultrahigh vacuum reduced the mechanical energy dissipation of the oscillating cantilever due to the removal of contaminants and natural oxide and reconstruction of the silicon surface. The Q-factor and influence of gas adsorption on ultrathin single crystalline silicon resonators having (100) and (111)-oriented surfaces were discussed.
