This study presents the polarization photodetection enhancement in Sb2Se3 nanotube (NT)‐based near‐infrared (NIR) photodetectors through simulation‐based and experimental investigations. High‐quality single‐crystal Sb2Se3 NTs are grown via chemical vapor deposition and characterized by using multiple techniques. The optical simulation reveals a remarkable difference in the light absorption ratio (specifically, absorption along the NT/nanowire (NW) against absorption perpendicular to the NT/NW) between Sb2Se3 NT and NW of the same size in the NIR region. The complementary photodetection experiments present that the fabricated Sb2Se3 NT photodetector demonstrates enhanced polarization photodetection in the NIR range, as indicated by a significantly increased dichroic ratio (3.03 at 850 nm) compared to that of similar‐sized NW counterpart (1.81 at 850 nm). Additionally, the Sb2Se3 NT photodetector exhibits exceptional performance, with a high responsivity of 4.18 A W−1 and specific detectivity of 8.94 × 1010 Jones under 830 nm light illumination. This study provides a comprehensive understanding of the microcavity resonance effect and its role in polarization photodetection enhancement, highlighting the potential of self‐assembled Sb2Se3 NTs in high‐performance near‐infrared polarized photodetection and other relevant applications.
