Figure 5From: Photovoltaic Ge/Si quantum dot detectors operating in the mid-wave atmospheric window (3 to 5 μ m)Measured responsivity and detectivity as a function of applied bias. For Ge/Si QDIPs whose PC spectra are presented in Figures2 and3. For the sample with bottom doping, the data were taken at λ = 3 μ m. For the sample with top doping, the peak responsivity and detectivity (λ = 3.4 μ m) are shown.Back to article page
