Comment on ‘‘Threshold switching in chalcogenide‐glass thin films’’

摘要

D. Adler, M. S. Shur, M. Silver, and S. R. Ovshinsky J. Appl. Phys.51, 3289 (1980) propose that field‐induced filling of traps may lead to S‐shaped negative differential conductance (SNDC), and use the existence of two solutions of electron concentration for a given applied field as evidence for it. We comment on the conditions for this existence of two solutions and its significance to the SNDC.
