Reliable and flexible field emitter for X-ray generation by implanting CNTs into Ni film using micromachining method

This paper reports a novel implanting Micromachining technology. By using this method, for the first time, we could implant nano-scale materials into milli-scale metal substrates at room temperature. Ni based flexible carbon nanotube (CNT) field emitters have been fabricated by a novel Micromachining method at room temperature. By embedding CNT roots into Ni substrate using polymer matrix as transfer media, effective direct contact between Ni and CNTs was achieved. As a result, our novel emitter shows relative good field emission properties such as low turn on field, high current density, and good stability. To check the practical application of the novel emitter, a simple X-ray imaging system was set up by modifying a traditional tube. The round grey pattern that appears on the sensitive film after exposing to the radiation confirms the successful generation of X-ray.
