摘要

报道了一种制备碳纳米管场发射极阵列的新方法。采用化学气相沉积(等离子体增强CVD和热CVD)和升空工艺在突起顶点上选择性生长CNTs。采用超高真空条件下的电流-电压曲线测量了碳纳米管阵列的场发射特性。结果表明,有Ti缓冲层的TCVD生长的碳纳米管阵列具有最佳的FE特性。

Selective growth of carbon nanotubes on silicon protrusions
A novel and simple process for fabrication of a carbon nanotube field emitter array is reported. Chemical vapor deposition (plasma enhanced CVD and thermal CVD) and lift-off process were used for selective growth of CNTs on the vertexes of the protrusions. The field emission measurements of the CNTs arrays were performed by taking current-voltage curves in an ultrahigh vacuum condition. It was found that the CNTs array grown by the TCVD with the Ti buffer layer gave the best FE characteristics.
