Universal Length Dependence of Tensile Stress in Nanomechanical String Resonators
Universal Length Dependence of Tensile Stress in Nanomechanical String Resonators
We investigate the tensile stress in freely suspended nanomechanical string resonators, and observe a material-independent dependence on the resonator length. We compare strongly stressed string resonators fabricated from four different material systems based on amorphous silicon nitride, crystalline silicon carbide as well as crystalline indium gallium phosphide. The tensile stress …
