Na-doped p-type ZnO microwires.
p-Type ZnO microwires were first synthesized by a simple chemical vapor deposition method using Na as the dopant source. p-Type doping was confirmed by the electrical transport in single-wire field-effect transistors and low-temperature photoluminescence. The carrier mobility of the microwires was estimated to be approximately 2.1 cm(2) V(-1) S(-1).
