Dr. Dennis Slafer, presenter at 2016 OLED Stakeholder Meeting Report on October 18-19, 2016

Dr. Dennis Slafer, R2R Manufacturing panelist at The Sixth Annual DOE Solid-State Lighting Manufacturing R&D Workshop on May 7–8, 2014

Partner, RedWave Energy, Inc., is the recipient of an ARPA-E grant for “High Speed Diode and Rectenna for Waste Heat to Electricity Harvesting”

RedWave Energy, Inc. will develop a rectenna-based device that can convert waste heat to electricity. The technology will incorporate special metamaterial structures, multiple nano- antennas, compensation circuit structures, and proprietary rectifiers. The proposed device will be demonstrated in large-area arrays, fabricated using nanoimprint lithography, thus enabling cost-effective roll-to-roll fabrication.

Partner, Iowa State University, is the recipient of an EERE grant for “Enhanced Light Extraction from Low Cost White OLEDs (WOLEDs) Fabricated on Novel Patterned Substrates”

ISU will demonstrate a way to increase the outcoupling of simple white OLEDs while maintaining a high color rendering index, by disrupting the internal waveguiding, using a unique and innovative corrugation pattern.

Issued Patents

Replication Tools and Related Fabrication Methods and Apparatus
Patent number: US 9395623

Abstract: Durable seamless replication tools are disclosed for replication of seamless relief patterns in desired media, for example in optical recording or data storage media. Methods of making such durable replication tools are disclosed, including preparing a recording substrate on the inner surface of a support cylinder, recording and developing a relief pattern in the substrate, creating a durable negative relief replica of the pattern, extracting the resulting durable tool sleeve from a processing cell, and mounting the tool sleeve on a mounting fixture. Apparatus are disclosed for fabricating such seamless replication tools, including systems for recording a desired relief pattern on a photosensitive layer on an inner surface of a support cylinder. Also disclosed are electrodeposition cells for forming a durable tool sleeve having a desired relief pattern. The replication tool relief features may have critical dimensions down to the micron and nanometer regime.

Roll-to-roll Patterning of Transparent and Metallic Layers
Patent number: US 9307648

Abstract: Systems and methods are disclosed by which patterns of various materials can be formed on flexible substrates by a continuous roll-to-roll manufacturing process. The patterns may include metallic, transparent conductive, or non-metallic elements with lateral dimensions including in the range from below 100 nanometers to millimeters and with thickness dimensions including the range from tens of Angstroms to greater than 10,000 Angstroms. The substrate may be any material capable of sufficient flexibility for compatibility with roll-based processing equipment, including polymeric films, metallic foils, and thin glass, with polymeric films representing a particularly broad field of application. Methods may include the continuous roll-to-roll formation of a temporary polymeric structure with selected areas open to the underlying substrate, the continuous addition or subtraction of constituent materials, and the continuous removal, where necessary, of the polymeric structure and any excess material.

Methods for Forming Patterns on Curved Surfaces
Patent number: US 9079349

Abstract: Methods are disclosed by which two-dimensional and three-dimensional pattern layers may be formed on non-planar surfaces, including optical elements such as lenses with one or more cylindrical, spherical or aspheric surfaces. Patterns with features in the micro- and/or nano-size regime comprised of organic, inorganic or metallic materials may be formed by the methods described herein.
