The effects of nonlocal impact ionization on the speed of avalanche photodiodes.

The effects of nonlocal impact ionization on the speed of avalanche photodiodes.

The nonlocal enhancement in the velocities of charge carriers to ionization is shown to outweigh the opposing effects of dead space, increasing the avalanche speed of short avalanche photodiodes (APDs) over the predictions of a conventional local model which ignores both of these effects. The trends...
