ZnO nanowires have attracted increasing interest due to its potential applications in electronics and optoelectronics
p-type doping of ZnO has a high concentration of nitrogen and a low-defect density
We demonstrate a versatile growth technique to synthesize phosphorus-doped ZnO (ZnO:P) nanowires in
a reproducible way
ZnO:P nanowires are synthesized via a vapor transport process based on a single source precursor, Zn3P2
The temperature at the source boat and the substrate were controlled at 500 C and 800 C
An alumina boat and a Si substrate were placed in a small quartz tube, separated typically by 7–10 cm.
This small quartz tube was then placed inside a horizontal tube furnace
ZnO nanocrystals were prepared by a chemical solution deposition (CSD)
The 0.75M precursor solution was deposited onto the Si substrate by spin coating
The as-deposited films were then preheated on a hotplate at 300 C for 10 min. Finally the sample was annealed at 500 C for 1 h.
ZnO powder and graphite powder were ground together
and loaded into an alumina boat
