Three new sulphur-passivation techniques of GaAs surfaces are presented to solve the problem of longevity and durability. To explore the passivation mechanism, XPS in conjunction With other techniques are employed to study the chemical compositions of Ga and As atoms near the passivation filmlsubstr

X-ray photoelectron spectroscopy (XPS) has been used to study the nature and content of sulphur contained in coal samples from Assam. In each case two sulphur 2p (S 2p) peaks were observed. The 169-I 71 eV 2p peak corresponds to sulphate, whilst the 164-I 65 eV peak is assigned to S in iron sulphide
The Nls and 01s regions of gaseous N,N-dimethyl-p-nitroaniline have been studied by X-ray photoelectron spectroscopy. The Nls (-NO\*) peak is z 0.5 eV broader than the Nls (-NH,) peak, indicating the presence of intense, unresolved shake-up. A shake-up peak has been observed in the 01s region at 2.1
