Figure 3From: Defect-related hysteresis in nanotube-based nano-electromechanical systems Energy variation during inter-tube sliding of a (9,0)@(18,0) carbon nanotube with no defects (squares-solid line), with a hillock SI pair (diamonds-dashed line) or a di-vacancy (triangles-dotted line) on the inner (9,0) shell.Back to article page
