Internal Amplification of Current Pulses Inside a Reverse-Biased Pnipn-Structure

Abstract

We present computer simulations for a model of a nonlinear device, which in previous work we suggested to detect the passage of high-energy particles by measuring current oscillations having frequency larger than the frequency of successive events. The aim is to show that the device proposed can indeed perform the task for which it was designed.

Key Words:

• Multilayered semiconductor structure
• drift-diffusion model
• HEP detector
• spatiotemporal dynamics

K.A. Lukin

Konstantin A. Lukin received the Diploma-Engineer degree in 1973 from Kharkov State University, Ukraine, USSR. Since 1973 he has been with the Institute of Radiophysics and Electronics, National Academy of Sciences of Ukraine, Kharkov. He received his Candidate of Sciences (mathematics and physics) degree in 1980 from Moscow State University, and the Doctor of Sciences (mathematics and physics) degree in 1989 from Kharkov State University. Both dissertations were devoted to theory of nonlinear processes in millimeter-wave vacuum electron devices. He is author and co-author of more than 60 journal publications in this field. His current research interests are nonlinear dynamics of various physical systems with delay feedback, and generation and processing of chaotic⁄noise waveforms and their applications. Currently his main activities lie in the field of noise radar technology and its applications.

H.A. Cerdeira

Hilda A. Cerdeira graduated as Licenciada en Fisica from the Universidad Nacional de Buenos Aires and holds a Ph.D. in physics from Brown University. She was Professor at the University of Campinas, Brazil, before moving to Italy. At present she is a Scientific Member of the Condensed Matter Group of the Abdus Salam ICTP Theoretical Physics, and is also Head of the Donation Programme of the Abdus Salam International Centre and Third World Academy of Sciences. For a number of years she shared the chairship of the Adriatico Research Conferences with Professor Stig Lundqvist. She works in nonlinear dynamical systems, in particular in synchronization of chaotic systems, where her work on decoding signals masked in low-dimensional chaotic signals is one of the milestones of the field. She is a member of the editorial board of the International Journal for Bifurcation and Chaos and of the World Scientific Series on Lectures in Complex Systems. She is a member of the IUPAP working group on Communications in Physics.

A.A. Colavita

Alberto A. Colavita graduated in physics from the Universidad Nacional de Cuyo and obtained his Ph.D. at Washington University, Saint Louis, in 1974. He has taught physics for almost 20 years and is now Professor of Computer Architecture at the Universidad Nacional de San Luis and Director of the Microprocessor Laboratory of the ICTP at Trieste, Italy. He is presently developing the high-speed data acquisition system for the RICH detector of the Compass collaboration. The Compass experiment uses the SPS accelerator at CERN.
