Description

Modeling and simulations of GeSn APDs (avalanche photodiodes) with tin content beyond 12% for the mid-infrared. Experimental measurements of the performance of such photodiodes under different operating conditions (voltages, temperatures, etc.). The parameters to be measured include responsivity at different wavelengths (up to about 3.5 μm), noise, gain, bandwidth, etc. Following the simulations, the model should be improved to better reproduce the performance of these devices, with a view toward subsequent new fabrication.
