Enhanced field emission of self-organized laser-produced Si and Ni micro-tip arrays with incorporated carbon nanotubes

摘要

Fromation of self-organized Si micro-tip effective field electron emission arrays using laser beam evaporation have been reported recently [1]. Simple production method of the quazi-periodical micro-tip arrays, which does not require any lithographic and microelectronic procedures [2], allows to form field electron emitters with very low emission threshold field of 1-5 V/μm. However, the emission uniformity for such arrays was not high enough for technical applications and required for further development.
