Overview

This study demonstrates a novel phototransistor that improves responsivity and detectivity for near-infrared applications, indicating breakthrough potential in sensor technology.

Key Points

The proposed VFEPT achieves a responsivity of 256 A W–1, significantly higher than conventional NIR photodiodes.
Detectivity reaches 2.5 × 10^15 Jones at 1550 nm, showcasing exceptional performance in low-noise environments.
This device integrates a mixed PbSeQD-HfO2 NP sensing layer and porous Au nanowire, optimizing charge accumulation.
The unique geometry and material pairing effectively reduce dark current and enhance signal detection for practical applications.
