研究目的
Investigating the impact of silver nanogratings for enhanced light absorption in plasmonic based photodetector.
研究成果
The design with rectangular gratings provides maximum quenching factor of 73.9%, indicating enhanced light absorption in the near infrared region. This is attributed to the rectangular groove shape providing maximum surface for light trapping, leading to minimal light loss as reflection.
研究不足
The study is limited to the analysis of silver nanogratings and does not compare with other metals extensively. The simulation is based on specific software and may not account for all real-world variables.
1：Experimental Design and Method Selection:
The plasmonic based photodetector is designed with silver nanogratings and analyzed over varying shapes like rectangular, trapezoidal, ellipse and parabolic taper using OptiFDTD software based on FDTD method.
2：Sample Selection and Data Sources:
The design parameters include groove shapes, input wavelength, nanogratings height, aspect ratio, subwavelength aperture height and width, semiconductor substrate, and subwavelength aperture material.
3：List of Experimental Equipment and Materials:
OptiFDTD software for simulation.
4：Experimental Procedures and Operational Workflow:
The structure design is simulated with varying parameters to analyze the light absorption enhancement factor (LAEF) and quenching factor.
5：Data Analysis Methods:
The LAEF and quenching factor are calculated to evaluate the performance of the photodetector.
