In this study, we achieved remarkable detection over a wide range of wavelengths, exhibiting distinguished responsivity with tenfold enhancement compared to the state-of-the-art. Light acquisition for long NIR wavelengths became possible through a single, tunable device. This research builds upon a comprehensive array of experimental results, encompassing devices with diverse geometries and multiple interlayers, including Au, Ti, and Cr schottky metals. These findings provide valuable design guidelines for optimizing device structures and insights into their application for various scenarios. Our emphasis lies in the extension of the spectral range for reconstructive spectroscopy into longer NIR wavelengths, fostering enhanced understanding and application possibilities.
