Catalyst and Temperature Dependent Growth of Silicon Nitride Micro/Nanoribbons

Abstract

One-dimensional micro/nanostructured silicon nitrides have attracted significant interests because they are potentially important for many applications due to its high stability, chemical inertness and capability for high-concentration doping. In this paper, single crystalline Si3N4 micro/nanoribbons were synthesized by catalyst-assisted pyrolysis of a polymeric precursor. The effects of catalyst and processing temperature on the morphology of the ribbons were investigated. The results revealed that both parameters can significantly influence the morphology of the ribbons, suggesting one-dimensional Si3N4 can be grown in a controllable manner by tailoring the processing conditions.
