- Аннотация: Electromechanical self-oscillations were induced during field emission from the lateral surface of a twisted nanotube yam obtained by solid-state spinning from a forest of vertically aligned multi-wall carbon nanotubes (CNT). Oscillations at several kilohertz frequencies were driven by applying a constant voltage between fixed opposite ends of the nanotube yam and a flat anode. An electromechanical model is developed which explains the observed phenomenon. The model is equally applicable to any mechanically flexible field emitter including sin-le nanoemitters like CNTs, which have shown a self-oscillating behaviour in several previous in situ experiments. This phenomenon opens a possibility of developing a new type of devices for conversion of DC voltage into the high frequency electromagnetic oscillations utilizing flexible nanoemitters.
