Abstract

In this article, a new semi-continuum model is built to describe the fundamental vibration frequency of the silicon nanowires in orientation. The Keating potential model and the discrete nature in the width and the thickness direction of the silicon nanowires in orientation are applied in the new semi-continuum model. Based on the Keating model and the principle of conservation of energy, the vibration frequency of the silicon nanowires with the triangle, the rhombus, and the hexagon cross sections are derived. It is indicated that the calculation results based on this new model are accordant with the simulation results of the software based on molecular dynamics (MD).
