Effects of Dead Space on Avalanche Gain Distribution of X-Ray Avalanche Photodiodes

IEEE Transactions on Electron Devices, 2012
A random path length model for X-ray avalanche photodiodes (APDs) has been used to assess the effects of carriers' dead spaces and injection position on the avalanche gain distributions. Significant carrier's dead space, typically found in submicrometer avalanche regions, is found to reduce spread in the avalanche gain distribution, which is consistent

The Effects of the Electrodes on an Electron Avalanche†

International Journal of Electronics, 1966
ABSTRACT The influence of the electrodes of a uniform field discharge gap on an electron avalanche ore discussed in. this paper. The presence of both electrodes reduces the number of electron/atom collisions in their vicinity thereby increasing the mean electron energy above the equilibrium valuo (∊). There is an associated decrease in the transit time

Crosstalk effects of avalanche CMOS photodiodes

2011 IEEE SENSORS Proceedings, 2011
This work explores crosstalk effects of avalanche CMOS photodiodes in a 3D sensor array where photodiodes were implemented under different shapes, perimeters, areas, structures and array sizes using the TSMC 0.35µm technology. The breakdown voltages are increased with areas and depths of p-n junctions, and decreased as perimeters of p-n junctions and ...

Creation of Interface States by Avalanche Effect

6th Annual Reliability Physics Symposium (IEEE), 1967
Charge and interface states are introduced into the oxide in an MOS capacitor by producing avalanche break-down at the semiconductor surface. Both the charge trapped in the oxide and the interface states can be annealed out at low temperatures.

Effect of Nonlinear Avalanche Process in Impatts

10th European Microwave Conference, 1980, 1980
An intrinsic limitation en maximum rf modulation has been shown to arise in the avalanche region of the diode. Narrow avalanche region diodes can have high rf modulation and hence high efficiencies. The nonlinearity of ionization process gives rise to a new rectification effect termed as 'abnormal rectification' for small values of avalanche region ...

The Effects of Training on the Risk of Avalanche Fatality

1999
The fatal hazard of avalanches is obvious; however, there are no satisfactory solutions for prevention. For many years skiing and mountaineering associations have endeavored to increase mountaineering safety by information programs and instruction courses.

An effective method for detection and elimination of avalanche effect problem

2010 IEEE International Conference on Mechatronics and Automation, 2010
The Supervisory control theory (SCT) is a general framework for the synthesis of supervisors (controllers) for discrete events systems (DES). The SCT makes use of automata theory and formal languages. Given a plant automaton model and a specification for the controlled behavior, a RW (Ramagde-Wonham) supervisor is obtained as an automaton. Programmable

Dynamic Effects of Avalanche-Generated Carriers.

1979
Abstract : Dynamic effects of avalanche-generated carriers in transistors were investigated using a two-dimensional, time-domain computer program. Basic properties of MESFET logic devices were also studied. The primary effect of avalanche process on bipolar transistor was found to be the majority carrier current in the lateral direction of the base ...

Temperature effects in silicon avalanche diodes

Solid-State Electronics, 1974
Abstract Gain-voltage curves for reach-through avalanche photodiodes are computed using the ionization rate data of van Overstraeten and de Man and Lee et al. and compared with measured curves. Noise spectral density measurements are also made and compared with McIntyre's avalanche noise theory.
