Probing Surface Information of Alloy by Time of Flight-Secondary Ion Mass Spectrometer
Crystals, 2021 In recent years, time of flight-secondary ion mass spectrometer (ToF-SIMS) has been widely employed to acquire surface information of materials. Here, we investigated the alloy surface by combining the mass spectra and 2D mapping images of ToF-SIMS.
