Facet-Engineered (100)-Oriented MoO₂ Nanoribbons for Broadband Self-Powered Photodetection.

ABSTRACT: Broadband photodetection plays a vital role in aerospace applications, biomedical imaging, and advanced communication systems. While molybdenum dioxide (MoO₂) exhibits exceptional electrical conductivity, carrier mobility, and environmental stability, its potential for photodetection has remained unrealized, with existing literature reporting negligible optoelectronic responses. Here, we unlock latent photoresponsivity of MoO₂ by facet engineering, demonstrating that exposing the (100) crystallographic plane activates its intrinsic photoelectric conversion. Using atmospheric-pressure chemical vapor deposition, we successfully fabricated large-area arrays of (100)-oriented MoO₂ nanoribbons. The resulting flexible photodetector on polyethylene glycol terephth
