Modeling Growth and Plasma Oxygen Effects on Metal Purity in Platinum EBID

Alberto Bramati, Antonio Balena, Hanna Le Jeannic, Linda Piscopo, Marianna D'Amato

EBID platinum deposits follow a hindered exponential growth model tied to beam parameters, with oxygen plasma treatment increasing platinum purity by removing carbon.

Claims

C1strongest claim

Using EDX, we establish a hindered exponential growth model that correlates deposit composition with fabrication conditions. Post-treatment EDX analysis confirms a systematic increase in platinum content, while SEM inspection reveals nanostructure shrinkage due to carbon removal.

C2weakest assumption

That EDX measurements accurately capture the true bulk platinum-to-carbon ratio without surface sensitivity artifacts or beam-induced changes during analysis, and that the observed shrinkage and purity gain result solely from selective carbon removal rather than platinum loss or redeposition.

C3one line summary

Presents a hindered exponential growth model linking EBID parameters to deposit composition and demonstrates that 30 W plasma oxygen treatment for 30 minutes increases platinum content with nanostructure shrinkage.
