B-doped MgO nanowires were synthesized through impurity-assisted physical evaporation of a mixture of B and MgO with a small amount of Ga2O3. The B content in the mixture affectsthe morphology of MgO nanowires. B-doped MgO nanotubes and cubes were formed when B-rich mixtures were utilized. Ammonothermal treatment of as-synthesized B-doped products resulted in the formation of uniform BN coatings adherent to nanowire and nanotube surfaces. Thus a facile BN coating method was developed. Finally the growth mechanism of the present BN-coated one-dimensional nanostructures was proposed.

    Synthesis of germanium/silicon (Ge/Si) core/shell nanowire heterostructures is typically accompanied by unwanted gold (Au) diffusion on the Ge nanowire sidewalls, resulting in rough surface morphology, undesired whisker growth, and detrimental performance of electronic devices. Here, we advance...

    We present a kinetic growth model having a particular emphasis on the influence of the group V element on the preferred crystal structure of Au-catalyzed III-V nanowires. The model circumvents the uncertainty in the group V contribution into the overall liquid chemical potential. We show why the...

    While almost all Si nanostructures, including Si nanowires (SiNWs), Si nanocrystals, and Si nanotrench-like structures on a supra- or sub-10 nm scale exhibit self-limiting oxidative behavior, herein we report full oxidation of SiNWs 5 nm in diameter. We investigated the oxidative behavior of...
