Title:
ORGANIC CAPACITOR HAVING A VOLTAGE-CONTROLLED CAPACITANCE
Document Type and Number:
WIPO Patent Application WO2005020257
Kind Code:
A3
Abstract:
The invention relates to an organic capacitor having a voltage-controlled variable capacitance. The inventive capacitor comprises at least one first electrode, a second electrode and an insulation layer located therebetween. The inventive capacitor is characterized by having at least one first semiconductor layer, which is placed between the first electrode and the second electrode. A voltage is applied between the first and second electrode and acts upon the semiconductor layer so that at least one concentration of free charge carriers in this at least one first semiconductor layer is controllably varied by the applied voltage. The concentration of the charge carriers defines the capacitance of the capacitor.
