摘要

We report the first demonstration of: 1) wide-wavelength range, infrared transparent conductors (ITCs) made of silver nanowires (Ag NWs), and 2) ITC contact-integrated prototype, InAsSb mid-wavelength IR (MWIR) detectors. The Ag NW-based ITCs show optical transmittance () of ∼94% in the 0.9–2.5 μm wavelength range with a sheet resistance () of 19.1 Ω/□. of the Ag NW-ITC decreases slowly with increasing wavelength, resulting in ∼92%–87% at 2.5–8 μm (MWIR) and ∼87%–82% at 8–15 μm (LWIR). The Ag NW-based ITC makes good ohmic contacts on InAsSb-based MWIR detectors with contact resistance of <0.5 Ω · mm. The ITC contact-integrated prototype InAsSb IR detectors are front-side illuminated and show external quantum efficiency (QE) of >85% at 4.25 μm and 150 K. The measured external QE remains at the same high level regardless of detector fill factor. These results indicate that Ag NW-ITCs may enable future pixel scaling for front-side illuminated, high-density-format focal plane arrays without compromising QE, responsivity, and detector performance.
