Sentences with phrase «nanowire growth»

For instance, certain substrates on which the nanowires grow create conditions so that the nanowire growth orientation is dictated by the substrate's underlying crystal structure.

In the study, the researchers found that the gallium - nitride nanowire growth orientation strongly depended on the relative concentration of nickel and gold within the catalyst.

To achieve their control, the team focused on the catalysis which guide the nanowire growth.

Once we were able to induce nanowire growth, we started analyzing their composition and structure, which took another year of work.
