Enhanced performance of printed organic diodes using a thin interfacial barrier layer

Area of Science:

• Organic electronics
• Semiconductor device physics

Background:

• Fabrication of printed organic diodes.
• Characterization of organic interfacial layers.
• Schottky barrier formation in organic devices.

Discussion:

• The role of a thin organic interfacial layer (<10 nm) in forming a Schottky barrier.
• Impact of the interfacial layer on diode performance, specifically reverse current reduction.
• Analysis of forward characteristics above 1 V.

Key Insights:

• A thin organic interfacial layer effectively reduces reverse current by two orders of magnitude.
• Forward characteristics above 1 V remain largely unaffected.
• Achieved a rectification ratio of five orders of magnitude in printed organic diodes.

Outlook:

• Potential for printed organic diodes in applications requiring low reverse currents.
• Further optimization of interfacial layer engineering for enhanced performance.
• Integration of these diodes into flexible and printable electronic systems.
