Abstract: A method of assessing thermionic electron emitter quality, comprising heating a thermionic electron emitter to an emission temperature thereby causing the emitter to emit electrons, forming the electrons emitted by the emitter into an electron beam, directing the electron beam to an image detector thereby forming an image corresponding to electron emission from a surface of the emitter, and detecting a presence or absence in the image of a pair of intersecting bright band features, each band feature being formed from two parallel lines, the band features corresponding to crystal lattice planes of the emitter. The presence of one pair of intersecting bright band features indicates a single-crystal emitter. The absence of a pair of intersecting band features indicates an amorphous or contaminated emitter. The presence of more than a single pair of intersecting bright band features indicates a polycrystalline emitter. The method is particularly useful for rare-earth hexaboride emitters.

Abstract: A unique, environmentally-friendly micron scale autonomous electrical power source is provided in a configuration that generates renewable energy for use in electronic systems, electronic devices and electronic system components. The configuration includes a first conductor with a facing surface conditioned to have a low work function, a second conductor with a facing surface having a comparatively higher work function, and a dielectric layer, not more than 200 Angstrom thick, sandwiched between the respective facing surfaces of the first conductor and the second conductor. The autonomous electrical power source formed according to the disclosed method is configured to harvest minimal thermal energy from any source in an environment above absolute zero. An autonomous electrical power source component is also provided that includes a plurality of autonomous electrical power source constituent elements electrically connected to one another to increase a power output of the autonomous electrical power source.

Abstract: An emission enhancement structure having at least one energy augmentation structure; and an energy converter capable of receiving energy from an energy source, converting the energy and emitting therefrom a light of a different energy than the received energy. The energy converter is disposed in a vicinity of the at least one energy augmentation structure such that the emitted light is emitted with an intensity larger than if the converter were remote from the at least one energy augmentation structure. Also described are various uses for the energy emitters, energy augmentation structures and energy collectors in a wide array of fields, such as color enhancement, and color enhancement structures containing the same.

Abstract: A method is provided for producing an electrically-powered device and/or component that is embeddable in a solid structural component, and a system, a produced device and/or a produced component is provided. The produced electrically powered device includes an attached autonomous electrical power source in a form of a unique, environmentally-friendly structure configured to transform thermal energy at any temperature above absolute zero to an electric potential without any external stimulus including physical movement or deformation energy. The autonomous electrical power source component provides a mechanism for generating renewable energy as primary power for the electrically-powered device and/or component once an integrated structure including the device and/or component is deployed in an environment that restricts future access to the electrical power source for servicing, recharge, replacement, replenishment or the like.
