Fabrication of Vertically Aligned Single-Crystalline Boron Nanowire Arrays and Investigation of Their Field-Emission Behavior

Aligned single crystalline boron nanowire arrays are formed by thermal carbon reduction. The SEM image shows an array of boron nanowires (ca. 5 µm long) vertically aligned in high density on a Si substrate. These nanowires have a high enhancement factor, good emission stability, and can endure high...

Zusammenfassung:Aligned single crystalline boron nanowire arrays are formed by thermal carbon reduction. The SEM image shows an array of boron nanowires (ca. 5 µm long) vertically aligned in high density on a Si substrate. These nanowires have a high enhancement factor, good emission stability, and can endure high current, which suggest they are an excellent candidate for field‐emission applications.
