摘要
We report on the fabrication of p-type ZnO:N layers using radical-source molecular beam epitaxy and post-growth annealing of the samples. Plasma-activated oxygen and nitrogen fluxes are supplied via a single plasma cell. The combination of low growth temperature (350 - 400 degrees C), slightly O-rich conditions, and post-growth annealing in the range of 650 - 800 degrees C results in efficient nitrogen p-doping with Hall hole concentration 3 x 10(17) cm(-3). The details of the structural and the electrical characterizations of the films are discussed.
