Synthesis And Characterization Of Undoped And Mg-Doped Zno Nanorods By Hydrothermal Method For Photodetector And Led Applications

Undoped and Mg- doped zinc oxide (ZnO) nanorods (NRs) have great potential applications in the fields of optoelectronic devices. Therefore, it is very important to realize the controllable growth of these NRs and investigate their properties. In this dissertation, ZnO NRs were grow on ZnO-seeded p-S...
