    Abstract: In an embodiment, a method includes forming a first diamond layer on a substrate and inducing a layer of graphene from the first diamond layer by heating the substrate and the first diamond layer. The method includes forming a second diamond layer on top of the layer of graphene and applying a mask to the second diamond layer. The mask includes a shape of a cathode, an anode, and one or more grids. The method further includes forming a two-dimensional cold cathode, a two-dimensional anode, and one or more two-dimensional grids by reactive-ion electron-beam etching. Each of the two-dimensional cold cathode, the two-dimensional anode, and the one or more two-dimensional grids includes a portion of the first diamond layer, the graphene layer, and the second diamond layer such that the graphene layer is positioned between the first diamond layer and the second diamond layer.

    Abstract: Provided are electron emitters based upon diamondoid monolayers, preferably self-assembled higher diamondoid monolayers. High intensity electron emission has been demonstrated employing such diamondoid monolayers, particularly when the monolayers are comprised of higher diamondoids. The application of such diamondoid monolayers can alter the band structure of substrates, as well as emit monochromatic electrons, and the high intensity electron emissions can also greatly improve the efficiency of field-effect electron emitters as applied to industrial and commercial applications.

    Abstract: A cold-cathode electron source is formed that successfully achieves a high frequency and a high output. Embodiments include a cold-cathode electron source comprising emitters having a tip portion tapered at an aspect ratio R of not less than 4, thereby decreasing capacitance between the emitters and a gate electrode by a degree of declination from the gate electrode, such that the cold-cathode electron source is able to operate at a high frequency. Embodiments also include a cold-cathode electron source formed of a diamond with a high melting point and a high thermal conductivity, such that the emitters operate at a high current density and at a high output.

    Abstract: Diamond-like carbon based thermoelectric conversion devices and methods of making and using the same, which have improved conversion efficiencies and increased reliability. The device can include a cathode having a base member with a layer of diamond-like carbon material such as amorphous diamond coated over the cathode. A dielectric intermediate member can be electrically coupled between the diamond-like carbon material and an anode. Various additional layers and configurations can allow for improved performance such as multiple cathode layers and/or multiple intermediate layers. The thermoelectric conversion devices can be configured as an electrical generator and/or a cooling device and can be conveniently formed. In addition, the devices of the present invention do not require formation of a vacuum space and are typically completely solid throughout. As a result, the devices of the present invention are susceptible to mass production at reduced costs and have improved conversion efficiencies and reliability.
