High-speed Diode for Low-cost Organic Circuitry

Abstract (Set) The Johns Hopkins University seeks a partner to commercialize a new organic diode useful for constructing complex organic electronic circuitry. The diode utilizes polymer and inorganic oxide layers to achieve high-frequency alternating current (AC) rectification, an operational requirement for constructing complex electronic circuitry, such as organic radiofrequency identification (RFID) tags.

• Organic semiconductors have been considered as a rectifier, but have generally been too slow to operate on the high-frequency AC signals required for more complex circuitry.
• The novel design of the organic diode incorporates an organic polymer (such as pentacene) and zinc-oxide to form a p-n junction, which allows it to handle rectification at AC frequencies exceeding 15 MHz while maintaining a lower operating voltage in ambient environment conditions.
• Both active layers (the organic polymer and the ZnO) may be deposited by solution, making printing the diodes a viable manufacturing option.
• The achievable AC frequency rectification make the diode useful for integration into more complex circuitry that require high-frequency AC signals, such as organic RFID tags.
• The organic diode consumes less energy and handles rectification at frequencies higher than any other organic diode currently available.
