| Summary: | Through a facile low-temperature hydrothermal process, heterojunction light-emitting diode (LED) was
successfully fabricated by growing vertically aligned ZnO nanorods on ZnO seeded p-GaN substrate.
Structural measurement revealed that nanorods with wurtzite structure having a preferential orientation
along the (002) c-axis. The electrical measurements showed an excellent rectifying behavior with low
threshold voltage, which confirms the formation of a heterojunction diode. The electroluminescence
spectra showed that the intensity of blue emission at 400 nm increased with increasing forward bias
voltage. |
