Single‑Crystal Diamond Nanowires Embedded with Platinum Nanoparticles for High‑Temperature Solar‑Blind Photodetector (IMAGE)
Caption
- Single-crystalline diamond nanowires embedded with platinum nanoparticles were fabricated for high-temperature solar-blind photodetection.
- At room temperature, the photodetector's responsivity represents a 2000-fold enhancement compared to bulk diamond. At 275 °C, the device demonstrates a responsivity of 3098.7 A W-1, while maintaining excellent spectral selectivity.
- Multiple factors synergistically enhance performance, including one-dimensional carrier transport channels, deep-level defects, localized surface plasmon resonance effect, and localized Schottky junctions.
