The oxygen peaks in the spectra might suggest that indium–gallium alloys are more prone to oxidation as opposed to pure gallium. The carbon peaks in both spectra can be attributed the the GC substrate (a), and the conductive Scotch tape (b), respectively. The combination of the three experiments clearly indicates that the oxide shells are ...Web
