In the last decade, my technical work has been either in the growth and characterization of 2D materials, photonic curing of materials, or application of these in the field of flexible electronics. So, I am a big fan of this 2019 paper that brings these all together!
This collaborative project, involving the Air Force Research Laboratory, University of Illinois at Urbana-Champaign, University of Dayton, UES, Inc., and the University of North Texas, introduces an innovative method aimed at addressing one of the key challenges in the mass production of flexible electronics: the creation of high-quality 2D materials on flexible substrates at low temperatures.
This cutting-edge technique involves the deposition of amorphous MoS2 at room temperature, followed by a process of photonic crystallization. This strategy allows for the efficient and scalable production of ultra-thin 2D photodetectors directly on stretchable polydimethylsiloxane (PDMS) substrates. The transformation of MoS2 from an amorphous to a polycrystalline state is driven by the targeted absorption of broadband light, leading to localized heating that is precisely controlled to ensure crystallization without damaging the PDMS substrate, demonstrating the precision and effectiveness of this method.
The resulting photodetectors exhibit remarkable responsivity, maintaining their performance even under extensive tensile strains and through numerous stretching cycles, highlighting their potential for use in advanced flexible electronic applications.
