The molecular beam epitaxy growth, fabrication, characterization and device applications of III-nitride nanowire heterostructures on Si (111) are presented in this dissertation. By improving the epitaxial growth process, we have achieved, for the first time, p-type conduction of InN. We report on the observation of ambipolar transport characteristics of InN:Mg nanowires at room-temperature, providing unambiguous evidence that the Fermi level is fundamentally unpinned on the grown surfaces of InN. Furthermore, our work suggests that defects and the incorporation of impurities on the grown surfaces of InN are the primary causes of the commonly measured accumulation of electrons and Fermi-level pinning. We also report on the achievement of ele...
