摘要:
Vacuum diode-based devices, including vacuum diode heat pumps and vacuum thermionic generators, are described in which the electrodes are coated with an electride (11, 12). These materials have low work functions, which means that contact potential difference between cathode (1) and anode (2) may be set against the effects of space charge, resulting in an improved device whereby anode (2) and cathode (1) may be set at a greater distance from each other than has been previously envisaged.

A method of manufacturing an article with integral active electronic component comprising: using an additive manufacturing process to: a) form a non-electrically conductive substrate; b) form a non-electrically conductive perforated layer having an aperture; c) form electrically conductive anode and cathode elements spaced in the aperture; d) deposit a conductive electrical connection to each of the elements suitable for imparting an electrical potential difference between the elements; e) form a non-electrically conductive sealing layer atop the perforated layer so as to retain and seal the aperture in the perforated layer.
摘要:
A microdevice (10) has an electron emitter (14) including a memory (18) for accumulating electric charges corresponding to an input voltage (Vi), for emitting electrons corresponding to the electric charges accumulated in said memory (18); and an amplifier (16) connected to a power supply (22) and including a collector electrode (20) for capturing the electrons emitted from the electron emitter (14). The atmosphere between at least the electron emitter (14) and the collector electrode (20) is a vacuum. When the electrons emitted from the electron emitter (14) are captured by the collector electrode (20) of the amplifier (16), a collector current (Ic) flows between the collector electrode (20) and the electron emitter (14) to amplify the input voltage (Vi).

摘要:
A vacuum integrated electronic device (120) has an anode region (101) of conductive material; an insulating region (102, 104) on top of the anode region; a cavity (54) extending through the insulating region and having a sidewall (53); and a cathode region (109). The cathode region has a tip portion (51, 52) extending peripherally within the cavity, adjacent to the sidewall of the cavity. The cathode region is formed by tilted deposition, carried out at an angle of 30-60° with respect to a perpendicular to the surface of device.
摘要:
Embodiments of a method for forming a field emission diode for an electrostatic discharge device include forming a first electrode, a sacrificial layer, and a second electrode. The sacrificial layer separates the first and second electrodes. The method further includes forming a cavity between the first and second electrode by removing the sacrificial layer. The cavity separates the first and second electrodes. The method further includes depositing an electron emission material on at least one of the first and second electrodes through at least one access hole after formation of the first and second electrodes. The access hole is located remotely from a location of electron emission on the first and second electrode.
摘要:
An improved design for maintaining nanometer separation between electrodes in tunneling, thermo-tunneling, diode, thermionic, thermoelectric, thermo-photovoltaic, current limiting, reset-able fusing, relay, circuit breaker and other devices is disclosed. At least one electrode is of a curved shape whose curvature is altered by temperature. Some embodiments use the nanometer separation to limit or stop current flow. Other embodiments reduce the thermal conduction between the two electrodes when compared to the prior art. The end result is an electronic device that maintains two closely spaced parallel electrodes in stable equilibrium with a nanometer gap there-between over a large area in a simple configuration for simplified manufacturability and use to convert heat to electricity or electricity to cooling, or limit current flow, or interrupt current flow.
