Table 1 Binding energies (BE, ±0.1 eV) and full width at half maximum (FWHM) (±0.05 eV) data of individual components determined from curve fitting of S 2p and As 3d XPS spectra of as-deposited and illuminated by green (λ = 532 nm) laser As40S60, As45S55, and As50S50 nanolayers

From: Coherent Light Photo-modification, Mass Transport Effect, and Surface Relief Formation in AsxS100-x Nanolayers: Absorption Edge, XPS, and Raman Spectroscopy Combined with Profilometry Study
