Figure 11. (A) Schematic structure of SAM APD based on Au/WSe2/Ge[113]. (B) I-V curves for different wavelengths of illumination[113]. (C) Schematic view (left) and cross-sectional view of the APDs (right)[122]. SAM: separated absorption multiplication; APD: avalanche photodetector; I-V: current-voltage.
