Near infrared (NIR) light has been broadly applied in various fields such as biomedical diagnostics, optical communications, night visions, etc. Recently, the application of NIR has been greatly expanded for light detection and ranging (LiDAR) systems, which are essential for autonomous vehicles, drones, humanoid robots, etc. To date, NIR sensors are fabricated with inorganic materials with rigid natures. However, due to the paradigm shift to flexible electronics, NIR sensors need to have a flexibility for system integration. In this regard, organic NIR sensors have attracted keen interest because organic materials (films) can deliver good flexibility compared to inorganic materials. Our group has demonstrated NIR-sensing organic phototransistors (OPTRs) based on a brand-new gate-sensing layer concept. This presentation uncovers new approach for NIR-OPTRs by introducing polymeric triple layers (channel/dielectric/sensing) leading to a CDS structure. |
