The frequency distribution of the threshold voltage of bistable Cu₂O switching devices

Abstract

The frequency distribution of the threshold voltage of Ag-Cu,O-Ag switching devices was experimentally established. With a few switching cycles (n 5 150) distribution can be interpreted by a numerical Gauss distribution. Only a single, from electrode to electrode uninterrupted, channel is optically provable. A numerical Gauss distribution is usually no longer observed with a larger number of switching cycles. The entire frequency distribution, however, is composed of several partial collectives which can be individually considered as normal distributions. These contribute in differing degrees to the total frequency distribution. Several switching channels can be optically proved. The channels and the normally distributed partial collectives were allocated to one another.
