Surface spectroscopy studies of Pb monolayers on Si(111)
TL;DR: In this paper, the authors studied the adsorption process and the thermal desorption of Pb on clean Si(111)7 × 7 substrates using LEED and AES, and the growth kinetics followed a Stranski-Krastanov mode (2D adlayer + 3D islands).
Journal ArticleDOI
Surface core-level shifts of Si(111)7×7: A fundamental reassessment
Journal ArticleDOI
Experimental evidence for 400-meV valence-band dispersion in solid C60.
G. Gensterblum,J.J. Pireaux,Paul Thiry,Roland Caudano,T. Buslaps,Robert L. Johnson,G. Le Lay,V. Aristov,R. Gunther,Amina Taleb-Ibrahimi,G. Indlekofer,Y. Petroff +11 more
TL;DR: It is demonstrated that at the low photon energy of ħω=8.1 eV the k∥ resolution becomes sufficient to resolve two bands in the feature derived from the highest-occupied molecular orbital which show a dispersion of the order of 400 meV.
Journal ArticleDOI
Formation of noble-metal-Si(100) interfaces
Margrit Hanbücken,G. Le Lay +1 more
TL;DR: In this article, a comparison between noble metal/Si(100) and noble-metal/Si (111) interface properties is made, based on electron spectroscopy and microscopy.
Journal ArticleDOI
Comparative structural and electronic studies of hydrogen interaction with isolated versus ordered silicon nanoribbons grown on Ag(110)
María E. Dávila,Antonela C. Marele,P. De Padova,I. Montero,Franz Hennies,Annette Pietzsch,M. N. Shariati,José M. Gómez-Rodríguez,G. Le Lay +8 more
TL;DR: The geometry and electronic structure of two different types of self-aligned silicon nanoribbons (SiNRs) are investigated, forming either isolated SiNRs or a self-assembled 5 × 2/5 × 4 grating on an Ag(110) substrate, by scanning tunnelling microscopy and high resolution x-ray photoelectron spectroscopy.
