Electron excited Auger line shape study of ion-beam-mixed Pd–Au alloys

Electron energy loss spectroscopic investigation of polycrystalline Au, Pd and a Pd–Au alloy

“…This peak has been assigned to an interband transition between the top of the valence band (5d 5/2 ) and the bottom of the conduction band (5sp) in gold. It has also been shown in photoemission studies of gold-palladium alloys that upon alloying the 5d 5/2 band of gold hybridizes with the palladium 4d band [3]. The result is a broadening of the gold 5d 5/2 band and a narrowing of the palladium 4d band, which also moves away from the Fermi level [2].…”

“…Various surface science techniques can be used to obtain complementary information about the electronic structure of different alloys and compounds. For example, the filled densities of states of palladium-gold alloys have been studied using experimental techniques such as X-ray photoelectron spectroscopy (XPS) [1] and valence-band Auger electron spectroscopy (CVV, AES) [2,3], which typically probe different depths beneath the surface. Photoemission spectroscopy (PES) [4,5] has been used to measure the joint density of states and the unfilled density of states have been determined using Bremsstrahlung isochromat spectroscopy (BIS) [6].…”
