In Situ Au Nanoparticle Decorated Multilayer PdSe 2 Films for Enhanced Bolometric Photodetection
Abstract
Two-dimensional (2D) PdSe 2 is a promising thermosensitive material for uncooled infrared (IR) detectors, owing to its layer-tunable bandgap, robust ambient stability, and compatibility with CMOS technology. However, its temperature coefficient of resistance (TCR)─a critical figure of merit for bolometric performance─is compromised in ultrathin films by gas adsorption and deteriorates markedly with increasing thickness, limiting practical deployment. To overcome this trade-off, we develop an in situ Au nanoparticle decoration strategy, enabling the synthesis of ultrathin (
