Photo-induced Valence Changes Observed by Photoelectron Spectroscopy of Thin Films of l -Cysteine on Ag(100), (110), and (111) Surfaces Grown in Saliva-emulated Aqueous Solution

Infrared laser-induced valence changes of sulfur, oxygen, and nitrogen atoms of l-cysteine molecules attached to the surfaces of crystalline silver are investigated through photo-electron spectroscopy. The obtained spectra depend on the Miller index of the surface of the silver s...

Electronic Structure of Decoupled TaS 2 in (SnS) 1.15 (TaS 2 ) Studied by Angle-Resolved Photoemission Spectroscopy

We investigate the electronic structure of TaS 2 in the so-called misfit compound (SnS) 1.15 (TaS 2 ) by angle-resolved photoemission spectroscopy. Our results reveal that in contrast to 2H-TaS 2 , TaS 2 layer in (SnS) 1.15 (TaS 2 ) does not exhibit a three-dimensional character:...
