Formation and instability of silver nanofilament in Ag-based programmable metallization cells

ACS Nano. 2010 Sep 28;4(9):5414-20. doi: 10.1021/nn1010667.

Abstract

In this paper, we report on the formation and rupture of Ag nanofilament on planar Ag/TiO2/Pt cells using visual observation. During the forming process, the filament tends to stay very thin. Specifically, it is so thin that it breaks up into a chain of nanospheres (according to Rayleigh instability) right after the formation has been completed. Similar mechanical breakup may also impact vertically stacked cells, causing reliability concerns.
