Discussion

Novel heterostructure photodetectors show broadband response from 532–2200 nm, indicating potential for high-resolution imaging.

The device achieves a record-high responsivity of 353 mA/W and detectivity of 2.43 × 1011 Jones, showcasing superior performance.
Integration of PdTe2 quantum islands with PtTe2 and n-Ge allows for detection beyond Ge's intrinsic absorption limit.
Observational analysis reveals ultrafast rise/fall times of 14 μs/20 μs, indicating rapid signal processing capabilities.
This approach establishes a cost-effective platform for next-generation on-chip photonic applications.

Liu et al. (2025) studied this question.
