Nonlocal effects in thin 4H-SiC UV avalanche photodiodes [PDF]

, 2003
The avalanche multiplication and excess noise characteristics of 4H-SiC avalanche photodiodes with i-region widths of 0.105 and 0.285 mum have been investigated using 230-365-nm light, while the responsivities of the photodiodes at unity gain were ...

The breakdown flash of Silicon Avalance Photodiodes - backdoor for eavesdropper attacks? [PDF]

, 2001
Silicon avalanche photodiodes are the most sensitive photodetectors in the visible to near infrared region. However, when they are used for single photon detection in a Geiger mode, they are known to emit light on the controlled breakdown used to detect ...

Effect of dead space on avalanche speed [PDF]

, 2002
The effects of dead space (the minimum distance travelled by a carrier before acquiring enough energy to impact ionize) on the current impulse response and bandwidth of an avalanche multiplication process are obtained from a numerical model that ...

Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]

, 2005
The effects of impact ionization in the InGaAs absorption layer on the multiplication, excess noise and breakdown voltage are modeled for avalanche photodiodes (APDs), both with InP and with InAlAs multiplication regions.

An avalanche-photodiode-based photon-number-resolving detector

, 2008
Avalanche photodiodes are widely used as practical detectors of single photons.1 Although conventional devices respond to one or more photons, they cannot resolve the number in the incident pulse or short time interval.
