The quest to develop workable electromechanical mechanisms in the nanoscale has often been predicated on meeting the conditions of super-low damping. We show here that the use of periodic forces to drive sliding core/shell double-walled carbon nanotube architectures produces oscillating-displacement response characteristics that are far more complex than cantilever-based designs, which suggest that meeting the conditions of controllability is much more pertinent for such architectures. Knowledge of these characteristics is necessary to successfully create sliding core/shell oscillator architectures that are capable of operating at gigahertz frequencies. In this work, we investigated the cases of the core and shell having equal and unequal lengths; and show the merits of using the latter.
