1 Introduction Emerging technologies with global societal impacts in renewable energy, healthcare, information science, building and machine automation, and consumer applications require ubiquitous, uncooled, low-cost, and mechanically compliant photodetection technologies operating across the near- to short-wave infrared (NIR–SWIR, λ = 0.9–1.8 µm).[1-7] Despite widespread efforts in scientific and engineering disciplines, photodetectors operating beyond the cut-off of silicon (λc ≈ 1.1 µm)...
