Abstract: Diamond-like carbon field emission surfaces, including associated devices and methods for using such devices are disclosed. In one aspect, for example, a field emission surface is provided, including a smooth layer of diamond-like carbon disposed on a smooth substrate, the diamond-like carbon layer having a uniformly distributed ablation pattern configured to emit electrons. The diamond-like carbon layer should be smooth in order to allow the uniform distribution of the ablation pattern.
