Multicolor sensing of organic-inorganic hybrid heterostructure: From visible to invisible colors

Abstract

Photodetection of organic-inorganic hybrid heterostructures from visible to invisible ultraviolet and infrared rays is revisited with respect to their material properties aspect, device structure, and emerging applications. The approach of organic-inorganic hybrid heterostructures using two or more varied materials has been extensively attempted as the emergence of broadband photodetection covering multi-colors as well as ultraviolet to infrared rays has ignited considerable interest in new applications. This review provides a timely overview of the scientific relationship between materials engineering and incident light properties, a systematic classification of representative material combinations, and a particular focus on each principle's insights. We also summarize recently-presented applications in organic-inorganic hybrid heterostructure-based photodetectors according to the target light wavelength.
