Abstract
A method for characterizing a carbon overcoat is provided. The method includes performing electron energy loss spectroscopy (EELS) spectrum imaging for an area of a preselected carbon-based material and an area of the carbon overcoat to generate a reference EELS dataset and a carbon overcoat EELS dataset, respectively, and determining a carbon bonding content of the carbon overcoat based on the reference EELS dataset and the carbon overcoat EELS dataset.
