NEMS Resonantor

  1. Nov 28, 2004 #1
    NEMS Resonator

    I need a hint to help with my homework.

    The question:

    "A Si-Based NEMS resonator has dimensions length=150nm, width=5nm and thickness=5nm and an effective spring constant of 100Nm^-1 and natural frequency of vibration of 250MHz"

    I am looking for an equation linking the natural frequency to the effective spring constant, as for the first part of the question i have to show what would happen to them if the dimensions of the resonator were doubled.

    Any advice, been trawling the net and my notes for a while and no joy.
