Tailoring Hydrogenation to Enhance Defect Suppression and Charge Transport in Hydrogenated Amorphous Silicon for Flexible Photodetectors.

ABSTRACT: Visible-light photodetectors (VPDs) garner significant attention due to their diverse applications in optical communication. However, conventional VPDs struggle to achieve both transparency and flexibility, limiting their use in emerging technologies. Hydrogenated amorphous silicon (a-Si:H) offers a promising platform for flexible optoelectronics for compatibility with substrates, although temperature reduction causes degradation of electrical and optical properties due to insufficient hydrogen passivation. In this study, the effect of the hydrogen-to-silane (H₂/SiH₄; f ratio) gas is systematically investigated ratio on the microstructural, optical, and electrical properties of a-Si:H films synthesized at an ultra-low temperature of 90 °C using plasma-enhanced chemica
