                  Professor Jason Azoulay and his teamBreakthrough research on infrared optoelectronics conducted by polymer Professor Jason
                  Azoulay and his team at The University of Southern Mississippi (USM) is being highlighted
                  in the prestigious journal Sciences Advances.

                  The group’s paper, officially titled: “Broadband infrared photodetection using a narrow
                  bandgap conjugated polymer” appears in the June edition of the highly acclaimed scientific
                  publication.

                  Azoulay, associate professor in the School of Polymer Science and Engineering at USM,
                  points out that the detection of infrared light forms the foundation for many modern
                  scientific, industrial, energy, medical, and defense applications. Despite widespread
                  efforts in scientific and engineering disciplines, photodetection from shortwave-to-longwave
                  infrared (SWIR-LWIR, ~1-14 µm) remains dependent upon archetypal crystalline inorganic
                  semiconductor devices that are produced using complex manufacturing systems within
                  specialized fabrication facilities.

                  “These suffer from limited modularity, intrinsic fragility, high-power consumption,
                  require cooling to achieve reasonable performance, and – are largely incompatible
                  with silicon-based technologies,” said Azoulay. “These attributes and very high costs
                  are prohibitive for many applications and emerging technologies.”

                  Conjugated polymers are soft matter conductors that overcome critical manufacturing
                  and operational drawbacks inherent to inorganic materials.

                  Infrared technology“We have a long-standing effort in the development of infrared technologies based
                  on conjugated polymers and develop new materials, soft matter systems, and device
                  paradigms that enable optical to electrical transduction of infrared light,” said
                  Azoulay. “This work demonstrates the first example of a high-performance photoconductive
                  detector that used a conjugated polymer active layer that senses photons across the
                  SWIR-LWIR portion of the electromagnetic spectrum.”

                  Azoulay group members who contributed to the research include: polymer research scientist
                  Dr. Naresh Eedugurala, post-doctoral researcher Dr. Lifeng Huang, and graduate student
                  Kevin Mayer. They collaborated with Dr. Jarett Vella from the Sensors Directorate
                  at the U.S. Air Force Research Laboratory and Professor Tina Ng from the Department
                  of Electrical and Computer Engineering at the University of California San Diego.
                  Both are regarded as leading experts in infrared optoelectronics and organic-based
                  semiconductor devices.

                  Dr. Chris Winstead, Dean of USM’s College of Arts and Sciences, says that Azoulay’s
                  work has the potential to revolutionize infrared detection technologies for uses ranging
                  from consumer products to advanced sensor systems for scientific and defense applications.

                  “As an optical sensor developer myself, I know that there is a vast market for improved
                  infrared sensors. Scientific advances like this work from Dr. Azoulay’s lab can form
                  the foundation for a whole new generation of products,” said Winstead.

                  Azoulay notes that the project took approximately three years to complete, however,
                  the materials development aspect has been ongoing since he arrived at USM in 2014.
                  Azoulay serves as principal/corresponding author of the paper, while Vella and Huang
                  are co-first authors.

                  As Azoulay explains, the growth of new applications, performance requirements, and
                  needs for miniaturization has outpaced the capabilities offered by current materials,
                  devices, and manufacturing infrastructure; thereby limiting the development of new
                  technologies.

                  Emerging technologies having global societal impacts in renewable energy, healthcare/medicine,
                  information science, defense, building and machine automation, and consumer applications
                  require ubiquitous, lower-cost, and uncooled infrared photodetection technologies.

                  “Thus, there remains a need for new semiconductor materials with figures of merit
                  similar to inorganic materials, but that also provide significant cost reductions,
                  scalable fabrication, heterogeneous integration, uncooled operation, geometric forms,
                  and mechanical properties that are not available using current technologies,” said
                  Azoulay. “This work provides a fundamentally new platform for broadly applicable,
                  low-cost, ambient temperature infrared optoelectronics.”
