Characteristics of the translocation signals for 60 nt DNA: A. Spike rate increases with bias after a threshold that depend upon the particular CNT-the two devices here show spike signals above 0.1 (squares) and 0.4 V (circles). B. Spike amplitude (squares) increases linearly with bias, and is about 5% of the background current (circles). C. Distribution of the charge in each spike for the SWCNT in units of the electronic charge, e.
