LBLars Barnewitz HBHannah Boeckers ACAtul Chaudhary

Key Points

To examine and compare the thermal surface chemistry of different iron precursors on Fe seed deposits.
Utilized reflection absorption infrared spectroscopy to analyze surface reactions.
Analyzed three iron precursors: Fe(CO)5, Fe(CO)4A, and Fe(CO)4MA.
Conducted experiments on Fe seed deposits produced by electron beam induced deposition.
Identified distinct surface reactions for each iron precursor.
Demonstrated varying thermal stability and reactivity among the iron precursors.
Reactions were characterized by changes in infrared spectra, indicating specific chemical transformations.

Abstract

This study compares the thermal surface chemistry of Fe(CO)5, Fe(CO)4A (A = acrolein) and Fe(CO)4MA (MA = methyl acrylate) on Fe seed deposits produced by electron beam induced deposition (EBID)...
