• • Dark current density reduced to 3.1 μA/cm² at 0 V, a >3-fold improvement over unpassivated baseline, directly lowering power consumption and noise in eSWIR focal plane arrays.
• • Specific detectivity of 8.79 × 10⁹ Jones at 2.5 μm and responsivity of 0.79 A/W, enabling room-temperature operation competitive with cooled InGaAs detectors.
• • Response time of 19.6 μs and linear dynamic range >66 dB, supporting high-speed eSWIR imaging and spectroscopy without signal saturation.
• • R₀A product of 8.78 Ω cm² at 300 K and 6.16 kΩ cm² at 80 K, demonstrating a 700-fold improvement upon cooling, which is critical for low-noise astronomical and defense applications.
