Generation and characterization of copper nanowires, nanoparticles, and thin films by flow- limited field-injection electrostatic spraying

Nanoscale structures of copper including nanowires, nanoparticles, and thin films were produced using flow-limited field-injection electrostatic spraying (FFESS) combined with chemical vapor deposition (CVD). The FFESS system allowed for efficient vaporization and delivery of the CVD precursor. The system also allowed for control of the type of structures based on deposition parameters. X-ray photoelectron spectroscopy (XPS) data confirmed that the samples were pure copper.
