Figure 1From: Ultrafast nano-oscillators based on interlayer-bridged carbon nanoscrolls (a) a DWCNT and (b) a CNS with a SWCNT housed inside. Perspective view (left) and end view (right). When displaced from its equilibrium position along axial direction, the inner tube (red) can oscillate inside the outer tube (cyan) or CNS (cyan), at gigahertz of frequency.Back to article page
