Discussion

Analysis reveals enhanced photocurrent in Ge/Si photodiodes with plasmonic structures, suggesting applications in telecommunications.

Photocurrent increased by about two times in Ge/Si photodiodes with plasmonic metal compared to bare samples.
Enhanced photocurrent observed at telecommunication wavelengths demonstrates the effect of surface plasmons.
Study utilized angular dependence measurements to explore optical mode dispersion from metastructures.
Results indicate significant potential for improving photodiode efficiency in future communication technologies.

Yakimov et al. (2025) studied this question.
