What is it about?

This article discusses how specific metallioc photonic crystal structures can be used to create improved sensors and optoelectronic devices. Metallic nanostructures have the potential for precise sensing because they can interact with their surroundings. However, these structures often produce broad and less effective signals. The study introduces a novel approach using a 2D-metallic photonic crystal slab (2D-mPhCs) to enhance the quality of the signals while keeping the fabrication process simple. This innovation is particularly useful in sensing applications, where the "figure of merit" (FOM) is a critical measure of performance. The study confirms that the hybrid structures created using this method offer a significantly improved FOM compared to traditional approaches, making them valuable for various applications, including photodetection and photocatalysis.
