Angle-resolved photoemission spectroscopy (ARPES), using HeI radiation, has been used to probe the occupied electronic states from a single domain of the Au-induced 5 x 2 reconstruction of Si(lll), a quasi-one-dimensional (quasi-1D) metallic system. The AR ...
Experimental Al KL(23)V and Ni LMM Auger and high-resolution valence band XPS spectra of Al3Ni and AlNi3 alloys are presented and compared to the corresponding spectra of pure metals. The spectra are interpreted in terms of the results of the discrete-vari ...
Photoelectron spectroscopy with high-energy resolution has been utilized to investigate the charge-density wave (CDW) in 1T-TaS2 between 20 and 360 K. Constant binding-energy curves reveal discontinuities in the temperature dependence of the photoelectron ...
A study of the formation of In- and Au-GaAs(100) interfaces is reported. The metal overlayers are deposited in ultrahigh vacuum on room-temperature (RT) and low-temperature (LT) (100)GaAs grown by molecular-beam epitaxy, following the evaporation of a prot ...
Angle-resolved photoemission spectra taken with high energy resolution on the one-dimensional compound (TaSe4)2I confirm the suppression of the spectral intensity at the Fermi edge for one-dimensional systems and lend support to correlation effects as its ...
We report a high-resolution core-level spectroscopy study of the (4 x 2)-c(8 x 2) GaAs(100) surface prepared by thermal decapping of surfaces grown by molecular-beam epitaxy. Ga and As 3d core levels are analyzed using very strict parameter conditions, and ...
A comparative study has been made of iodine-intercalated Bi2Sr2Ca1Cu2Ox single crystal and 1 atm O2 annealed Bi2Sr2Ca1Cu1Ox single crystal using an AC susceptibility measurement, X-ray photoemission (XPS) and angle-resolved ultraviolet photoemission spectr ...
Photoelectron spectroscopy reveals a striking correspondence between charge-density-wave-related phase transitions and modifications of the electronic structure in 1T-TaS2. High-energy-resolution spectra indicate that the collapse of the Fermi surface is a ...
The authors report experimental evidence for an enhanced density of states at the Fermi level in Al86Mn14 and Al75Mn20Si5 quasicrystals (QC) as indicated by the low-temperature specific heat and resistivity. The excess specific-heat term Δγ is proportional ...
High-energy-resolution photoemission spectra, taken on three quasi-one-dimensional crystals, TaTe4, NbTe4, and (NbSe4)3I confirm the general phenomenon of the suppression of the photoemission intensity near the Fermi level in one dimension. We analyze the ...
