B. Current Density (J)
The maximum current density is about 6.115 xl 02 Alm2 as
shown in Fig. 3 simulation results. This maximum current
density is significantly higher than conventional power diode
made from silicon [21 ]-[31]. Moreover, CNT can handle high
current density because it possesses tremendously high surface
area and linear geometry [15]-[21]. The (I-V) characteristic of
BSWCNT-based power diode is closer to the ideal
characteristics as demonstrated in Fig. 4.
