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.
