Experimental results (open cycle) and theoretical linear fitting (solid line) of I-V characteristics in positive voltage region. (a) Linear relationship of logI versus logV1/2 in the voltage region of 0 to 7 V (OFF state); (b) linear fit in double logarithmic scale in the voltage region of 7 to 10 V (OFF state); (c) linear fit in double logarithmic scale at voltage region of 10 to 0 V (ON state).
