Multilayer films of exfoliated 2D oxide nanosheets by electrospray deposition

The potential of the electrospray deposition technique as new method to make nanosheet-based multilayer films is evaluated. Densely packed nanosheet-based films with thicknesses of 1-20 nm with rms roughnesses of 2.1-2.4 nm were fabricated on samples of 1 cm(2) size with a growth rate of 0.5 nm/min. Electrosprayed Ti0.87O2 nanosheet films were successfully used as oriented growth templates for 40 nm perovskite SrRuO3 thin films grown by pulsed laser deposition. The electrospray method provides a fast and easy alternative to the more commonly used Langmuir-Blodgett (LB) deposition method for nanosheet films.

Automated summary

In this study, the potential of the electrospray deposition technique as a new method for fabricating nanosheet-based multilayer films was evaluated. Densely packed nanosheet-based films with low roughness were successfully fabricated, and the electrospray method also proved to be a suitable growth template for perovskite thin films. The electrospray method offers a fast and easy alternative to the commonly used Langmuir-Blodgett deposition method.
