Beryllium, Be – Info & Basic Spectra
XPS Information about Beryllium, Be
Primary XPS Signal: Be (1s) (~112 eV)
Overlapping Signals: Cu (3s), Ni (3s), Au (5s)
Binding Energies of Chemical States:
|Chemical State||Be (1s) Binding Energy (eV)|
|Cu(x)-Be(y), as received||113.3 eV|
|Cu(x)-Be(y), Ar+ etched||112.5 eV|
Data Collection Advice & Information
- Be (1s) peak has very low signal sensitivity.
- Recommend 10X longer data collection when acquiring Be (1s) spectrum.
Interpretation of Be Spectra
- There are no secondary peaks to confirm presence of Be
- Difficult to confidently assign Be1s peak for low concentrations.
