Once the complete bunch is within the ion lift tube, the potential is rapidly switched to a negative voltage U lift When leaving the lift, a potential barrier has to be overcome, which causes the kinetic energy of the ions to decrease Along the deceleration path, the ions move through a tensegment lens system to prevent defocusing of the ionFigure 2(a) shows I–V curves from the nanodiodes annealed at different temperatures All of the I–V curves were recorded at room temperature To obtain characteristics of the potential barriers at the Au–TiO 2 and TiO 2 –Ti interfaces before and after annealing, the I–V curves were fitted to the Simmons' equation 24, 25In this article, we have used a highly doped silicon single electron transistor (SET) and show that an additional localization process may lie at the tunnel barrier Caused by natural defects or more generally, by an asymmetry in the barrier shape, the effect can enhance significantly the electron trapping mechanism In the first section, we discuss the observation of a negative differential
