Capacitive Engine Featuring An Extrinsic Semiconductor

Abstract

The capacitive engine is an asymmetrical capacitor which produces a net non-zero electrostatic force when a voltage difference is applied between the two conductor-semiconductor contacts of an incompletely spherical extrinsic semiconductor shell. At least one Schottky barrier is made from one of the conductor-semiconductor contacts at either of the extrinsic semiconductor's inner or outer radius and is always in reverse bias. Since the Schottky barrier is always in reverse bias, the reverse biased Schottky barrier becomes an electronic capacitor mimicking the shape of the incompletely spherical shell of the extrinsic semiconductor. A net non-zero electrostatic force is thereby produced because the inner and outer radial surface areas of the electronic capacitor have a non-zero difference and this difference is multiplied by the relative electrical permittivity of the incompletely spherical extrinsic semiconductor shell when calculating the net electrostatic force of the capacitive engine.
