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.
