Preparation, structural and temperature dependence of optical property of ZnO nanostructures on seeded porous silicon / Kevin Alvin Eswar

In this work, ZnO nanostructures were grown on seeded porous Silicon (PSi) template. There were two stages in this study; the preparation of seeded PSi template in the first stage and the deposition of ZnO nanostructures on seeded PSi in the second stages. The first stage was involved the preparatio...
