WebApr 7, 2024 · At an increase in the width of the absorption region, the quantum efficiency increases while the performance decreases. Experimental studies show that the absorption region length should be 1–2 μm while the multiplication layer thickness should be ∼10 times smaller, which allows work at relatively low reverse bias voltages. http://www.christou.umd.edu/documents/PhysicaB-Calculations.pdf
