Abstract
In accordance with one embodiment of the present invention, a Gap Diode is disclosed in which a tubular actuating element serves as both a housing for a pair of electrodes and as a means for controlling the separation between the electrode pair. In a preferred embodiment, the tubular actuating element is a quartz piezo-electric tube. In accordance with another embodiment of the present invention, a Gap Diode is disclosed which is fabricated by micromachining techniques in which the separation of the electrodes is controlled by piezo-electric, electrostrictive or magnetostrictive actuators. Preferred embodiments of Gap Diodes include Cool Chips, Power Chips, and photoelectric converters.
Claims12
A diode device comprising:
- a first electrode;
- a second electrode, separated from said first electrode by a distance;
- an electrical circuit connected to said first and second electrodes;
- a tubular housing having a further pair of electrodes attached to an inner and outer face and attached to controlling circuitry whereby a length of said housing may be modified by a signal applied to said further pair of electrodes, and wherein said first electrode is attached to one end of said housing and said second electrode is attached to an opposing end of said housing to form a sealed device;
- and
- wherein said housing consists of an actuating element whereby the magnitude of said distance may be adjusted.
