    Abstract: Diamond-like carbon based devices and methods of making and using the same which have improved electron emission and increased reliability. The device can include an anode with a layer of diamond-like carbon material such as amorphous diamond coated over at least a portion of the anode and a cathode. An intermediate member can be electrically coupled between the diamond-like carbon material and the cathode. Various additional layers and configurations can allow for improved performance such as multiple cathode layers and/or multiple intermediate layers. The presence of diamond-like carbon on the anode provides significantly improved electron emission with or without diamond-like carbon on the cathode. The devices can be configured as thermoelectric conversion devices such as an electrical generator or a cooling device, light emitting devices, or other electronic devices and can be conveniently formed.

    Abstract: An electron emission element of the present invention comprises a substrate, and a protrusion protruding from the substrate and including boron-doped diamond. The protrusion comprises a columnar body. And a tip portion of the protrusion comprises an acicular body sticking out therefrom. The distance r [cm] between a center axis and a side face in the columnar body and the boron concentration Nb [cm−3] in the diamond satisfy the relationship represented by the following formula (1): r > 10 4 Nb .
