Log-log plots of the
curves and the fitting parameters. (a) Log-log plots of the I-V curves of the individual CdS microrope at different temperatures. The symbols are the experimental points, while the solid lines are the fitting lines to I ∞ V
M of the SCLC model. (b) The fitting parameters M
2 (at higher voltages) of the SCLC model (I ∞ V
M) and M
1 (at lower voltages) of Ohm's characteristic from 360 down to 60 K.
