Figure 4From: Ultraviolet/blue light-emitting diodes based on single horizontal ZnO microrod/GaN heterojunctionThe linear dependence and the carrier transports and recombination mechanisms. (a) Plots of ln(J · F) versus E−1and ln(J/E3) versus E−1of the n-ZnO/p-GaN heterojunction LED at reverse breakdown bias. (b) The band diagram of the p-GaN/n-ZnO heterojunction under the reverse breakdown bias.Back to article page
