This paper reviews the mechanisms underlying visible light detection based on phototransistors fabricated using amorphous oxide semiconductor technology. Although this family of materials is perceived to be optically transparent, the presence of oxygen deficiency defects, such as vacancies, located at subgap states, and their ionization under illumination, gives rise to absorption of blue and green...
We discuss the development of amorphous oxide semiconductor technology for optical sensor applications. In particular, we discuss the challenges of detecting visible wavelengths using this family of materials, which are known to be optically transparent due to their relatively large bandgap energy. One of the main issues with amorphous oxide semiconductors (AOS) is the ionization of the oxygen vacancies...
