Semiconductor Nanowire Metamaterial for Tunable Enhanced Absorption

Abstract

The development of a semiconductor adjustable absorber in the THz will open up new possibilities for quantum information science, imaging, health, and sensing applications, particularly those that need to be portable. Here, we build a unique semiconductor nanowire metamaterial that exhibit increased absorption efficiency at various temperatures by carefully organizing and shaping the semiconductor nanowire array. This discovery paves the way for the potential development of a new generation of THz quantum detectors that operate close to room temperature and offer exceptional improved absorption for a broader variety of applications.
