Abstract: A field emission cathode and methods for fabricating such a cathode from at least one body containing a first substance. The steps include a preparation of at least one irregularity in an emitting surface of the body, adding to the emitting surface of the body ions of a second substance with a low work function, and modifying the emitting surface by inducing field emission in applying a variable electric field to the body and increasing the field strength in steps.

Abstract: In the method of the present invention, electrostatic fields are used to induce heat pumping action of a working fluid. A plurality of heat pumps with no moving parts are used. The operation of the one pump enhances the operation of the next. The method of the present invention is conducive to devices of a wide range of scales. Furthermore, operation at partial power levels is practicable, and precise control of temperature possible. Control is further enhanced by the addition or removal of further units to the system. Reliability should be enhanced, and peak power demands reduced. Wide selection of possible working fluids allows for the elimination of environmentally harmful halocarbons. In one embodiment of the present invention, chemical working fluids are eliminated entirely. In another embodiment, supercooled fluids such as liquid helium may be used while eliminating the wastage commonly encountered using such fluids.

Abstract: An ionic liquid ion source can include a microfabricated body including a base and a tip. The body can be formed of a porous material compatible with at least one of an ionic liquid or room-temperature molten salt. The body can have a pore size gradient that decreases from the base of the body to the tip of the body, such that the at least one of an ionic liquid or room-temperature molten salt is capable of being transported through capillarity from the base to the tip.
