First Claim
Patent Images
1. A semiconductor device comprising:
- a polymer having at least one rectifying function produced by a layer of the polymer between first and second parallel electrodes, wherein;
the layer of the polymer includes a host matrix for polar molecules, the polar molecules are oriented perpendicular to the first and second electrodes, electrical charges of the polar molecules are aligned in a direction towards the first and second electrodes, and said orientation of the polar molecules induces an electric field inside the layer of the polymer.

Abstract
A semiconductor device made of polymer. The device includes at least one rectifying function formed by a layer of polymer between a first and a second electrode. The layer of polymer forms a host matrix for polar molecules with the polar molecules being electrically oriented in a direction perpendicular to the electrodes. The electrical charges of the polar molecules of the same sign are directed towards the same electrode. The method of producing such a device is also included.
