Fig. 4: Quantum efficiency and noise equivalent power measurements.

From: High-temperature mid-wavelength infrared avalanche photodiode with modified fully-depleted absorption and multiplication region

Fig. 4

a Measured unity-gain external quantum efficiency and responsivity of a 100 μm  × 100 μm APD device at 80 K and 160 K. b The noise equivalent power versus wavelength under 292 gain for 80 K and 189 gain for 160 K. The noise is based on the measured dark current under the −13 V bias.
