Abstract:

The authors presented a facile approach to prepare highly-ordered sub-micrometer scaled cylindrical  diamond arrays based on a chemical vapor deposition method, where the accurate control of the style of crystal seeds dispersion and the growth time are very crucial. The as-prepared diamond array showed good conductivity which was originated from the proper boron doping, and moreover, it exhibited good field emission property with low turn-on field and high emission current. Importantly, this approach can be easily applied to the preparation of various    micro-patterned one-dimensional diamond arrays.
