Avalanche multiplication Gain proportional to the applied reverse bias voltage can be obtained. P+ P- P High voltage N+ Avalanche layer KAPDC0006EC Si APD ( avalanche photodiode). Abstract: HgCdTe electron avalanche photodiodes ( e- APDs) have been widely used for low- flux and high- speed application. To better understand the dark current transport and electron- avalanche mechanism of the devices and optimize the structures, we performed accurate numerical simulations of the current- voltage characteristics and multiplication factor in planar homojunction ( p- i- n) HgCdTe APDs.

electron) may trigger an avalanche pulse which discharges the photodiode from its reverse voltage VR to a voltage slightly below VBR. The probability of this avalanche occurring is shown in Figure 8 as the " Photoelectron Detection Probability" and as can be seen, it increases with reverse voltage VR.
