Remarkable Noise Reduction in High-Stability Self-Powered Doped Graphene/Si-Quantum Dot Broadband Photodetectors by Using Graphene Quantum Dots as an Interlayer

“…Photodetectors (PDs) are extensively employed as crucial components in a variety of fields such as information technology, telecommunication, internet of things, scanning, medical diagnosis/treatments, and military sensing. − Large conductivity and good transparency of the electrodes for a PD are essential for its high performance especially in the visible light region. Among the multiple electrodes, graphene (GR) transparent conductive electrodes (TCEs) have already been employed in the area of optical detecting due to their excellent electrical/optical properties. , The fabrication of Schottky-junction PDs by a simple method of transferring GR to most-popular Si semiconductors is well known, − thereby showing better functionalities compared to their metal electrode-based counterparts. Nevertheless, the photoresponse is limited in its further enhancement owing to the large leakage current caused by relatively high-density defect states at the GR/Si interface .…”
