Figure 5From: Defect-related hysteresis in nanotube-based nano-electromechanical systems Energy variation during inter-tube sliding of a (6,6)@(11,11) carbon nanotube with a C SI (filled and open squares for sliding in opposite directions). The lines with almost vanishing values (filled circles) at the bottom are for the pristine case of no defects and for a single vacancy on the inner tube.Back to article page
