Abstract

Highlights

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
