In this paper, we have developed a new thermoacoustic model for predicting the resonance\nfrequency and quality factors of one-dimensional (1D) nanoresonators. Considering a nanoresonator\nas a fix-free Bernoulli-Euler cantilever, an analytical model has been developed to show the influence\nof material and geometrical properties of 1D nanoresonators on their mechanical response without\nany damping. Diameter and elastic modulus have a direct relationship and length has an inverse\nrelationship on the strain energy and stress at the clamp end of the nanoresonator. A thermoacoustic\nmultiphysics COMSOL model has been elaborated to simulate the frequency response of vibrating 1D\nnanoresonators in air. The results are an excellent match with experimental data from independently\npublished literature reports, and the results of this model are consistent with the analytical model.\nConsidering the air and thermal damping in the thermoacoustic model, the quality factor of a\nnanowire has been estimated and the results show that zinc oxide (ZnO) and silver-gallium (Ag2Ga)\nnanoresonators are potential candidates as nanoresonators, nanoactuators, and for scanning probe\nmicroscopy applications.
