HgCdTe avalanche photodiodes: A review High gain datasheet a low excess noise factor close to unity, above 5× 10 3, , MWIR, fast response in the range of pico- seconds has been achieved by electron- initiated avalanche multiplication for SWIR, , THz gain- bandwidth product LWIR detector applications involving low optical signals. The APD gain shown in Figure 5 was normalized to one at a bias voltage of 0. 7 capacitance the avalanche effect on the gain at moderate bias voltages. Abstract Under a hgcdte current award, NASA NNX 13AC13G " EXTENDING THE ASTRONOMICAL APPLICATION OF PHOTON COUNTING HgCdTe LINEAR datasheet AVALANCHE PHOTODIODE ARRAYS TO LOW BACKGROUND SPACE OBSERVATIONS" UH has used Selex SAPHIRA 320 x electron 256 MOVPE L- APD HgCdTe arrays developed for Adaptive Optics ( AO) wavefront ( WF) sensing to investigate the potential of this technology for low background space astronomy.

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.
