Abstract:
Large-scale PrB 6 nanowires were fabricated by an effective, catalyst-free, and a simple low-pressure chemical vapor deposition (LPCVD) process. These nanowires, characterized in detail by various analytical instruments, demonstrated the large aspect ratio and high single-crystalline
grown along the [001] crystal direction perpendicular to the (001) crystal plane. The field electron emission equipment tests manifest that the asgrown PrB 6 products have a low turn-on field ( E to , 2.32 V/ μ m), a threshold field ( E thr ,
4.28 V/ μ m), a high field enhancement factor ( β , 2336), as well as a stable current-density ( J ) of field-emission. The relationships of the field electron emission parameters, such as J , E to , and β versus cathode gap ( d ),
have been established when d is increased from 500 μ m to 800 μ m. The outstanding properties suggest that the PrB 6 products may be promising emitters in the cold-field-emission cathode application.
