Nonetheless, the high Al composition in the EBL could increasethe ing electron leakage. Nevertheless, the higher Al composition in the EBL could increase the forward voltage since the EBL also acted as an power barrierfor holes. In Figure 7a, forward voltage because the EBL also acted as an power barrier for holes. In Figure 7a, the V curves are compared for the compositions of 15 , 20 , and 25 . As As exthe V curves are compared for the Al Al compositions of 15 , 20 , and 25 . anticipated, pected, the forward voltage elevated together with the increasingAl composition in the EBL. This the forward voltage enhanced with the growing from the of the Al composition of the EBL. This trade-off partnership in between the electron leakage existing and forward voltage implies a implies a trade-off partnership amongst the electron leakage existing and forward variation inside the Al composition of your EBL.
