Carbon nanotubes (NTs) offer a unique opportunity to scale down Nano Electro Mechanical Systems (NEMS) to the nanometer scale. Here we present our recent results in which guitar-string-like oscillation modes of doubly clamped nanotube oscillators were found. These resonance frequencies can be widely tuned electrostatically and their quality factor increases as temperature decreases. The static behavior of suspended NTs is intriguing as well. We will discuss their electrical response to mechanical perturbations and magnetic fields.
