Suppressed Hysteretic Field Emission from Polymer Encapsulated Silver Nanowires

Abstract

Suppression of the hysteretic electron emission in one-dimensional nanomaterial-based electron sources remains a critical barrier preventing their wide scale adoption in various vacuum electronics applications. Here we report on the suppressed hysteretic performance, and its photo-dependence from conformal poly-vinylpyrrolidone (PVP) encapsulated percolative Ag nanowire (NW)-based electron sources.
