摘要：
Model of frequency-controlled carbon-nanotube oscillators are proposed and their dynamic properties are investigated via classical molecular dynamic simulations. Their operation frequencies can be changed by engineering the intertube gap, which dominantly affects their operating frequencies in the improved bandwidths rather than those achieved by initial velocity engineering.
