Excess Noise Factor of a-Si: H/a-SiC: H Separated Absorption and Multiplication Region Superlattice-like Avalanche Photodiodes (SAM-SAPDs)

چکیده
In this paper, an a-Si:H/a-SiC:H separated absorption and multiplication region superlattice avalanche photodiode (SAM-SAPD) using combined effect of band edge discontinuity and build-in potential in p-n junction is designed and fabricated successfully. The formula that describe the relationships among excess noise factor (Fe), mean multiplication ( e M ), and the ionization rate ratio (ks) for this SAM-SAPD are established theoretically. The comparisons between the theoretical calculations and the experimental results for Fe vs. Me are discussed.

Plasmonic field confinement for separate absorption-multiplication in InGaAs nanopillar avalanche photodiodes
Avalanche photodiodes (APDs) are essential components in quantum key distribution systems and active imaging systems requiring both ultrafast response time to measure photon time of flight and high gain to detect low photon flux. The internal gain of an APD can improve system signal-to-noise ratio (SNR). Excess noise is typically kept low through the selection of material with intrinsically low...
متن کاملExcess Noise in GaAs Avalanche Photodiodes with Thin Multiplication Regions
It is well known that the gain–bandwidth product of an avalanche photodiode can be increased by utilizing a thin multiplication region. Previously, measurements of the excess noise factor of InP–InGaAsP–InGaAs avalanche photodiodes with separate absorption and multiplication regions indicated that this approach could also be employed to reduce the multiplication noise. This paper presents a sys...

متن کاملExcess Noise Factors for Conventional and Superlattice Avalanche Photodiodes and Photomultiplier Tubes
Light falling on a photodetector produces an output current that fluctuates. The noise in this signal arises from two sources: randomness in the photon arrivals and randomness in the carrier multiplication process intrinsic to the photodetector. A general formula is derived for the variance of the photodetector output current in terms of parameters characterizing these two sources of randomness...

Previously, it has been demonstrated that resonantcavity-enhanced separate-absorption-and-multiplication (SAM) avalanche photodiodes (APD’s) can achieve high bandwidths and high gain–bandwidth products while maintaining good quantum efficiency. In this paper, we describe a GaAs-based resonant-cavity-enhanced SAM APD that utilizes a thin charge layer for improved control of the electric field pr...
