Spectroscopic evidence for spin-polarized edge states in graphitic Si nanowires

Autor: P C Snijders, P S Johnson, N P Guisinger, S C Erwin, F J Himpsel

Publikováno v: New Journal of Physics, Vol 14, Iss 10, p 103004 (2012)

The step edges on the Si(553)–Au surface undergo a 1 × 3 reconstruction at low temperature which has recently been interpreted theoretically as the ×3 ordering of spin-polarized silicon atoms at the edges of the graphitic Si nanowires on this vic

Tantalus, the First Dedicated Synchrotron Radiation Source

Autor: F. J. Himpsel, David W. Lynch, Ward Plummer, Giorgio Margaritondo, Gerry Lapeyre, Tai C. Chiang

Publikováno v: Synchrotron Radiation News. 28:20-23

Tantalus began as a 240 MeV electron storage ring that served as a testbed for the next-generation accelerator (which eventually would become Fermilab) [1, 2]. It was to be injected from the 40 MeV FFAG synchrotron that was already operating. Before

Helical versus All-Trans Conformations of Oligo(ethylene glycol)-Terminated Alkanethiol Self-Assembled Monolayers

Autor: Phillip S. Johnson, Nicholas L. Abbott, F. J. Himpsel, Mohit Goel

Publikováno v: Langmuir. 30:10263-10269

The complex mixture of conformational states exhibited by oligo(ethylene glycol)-terminated alkanethiols on Ag and Au surfaces is explored by polarization-dependent X-ray absorption spectroscopy. Three self-assembled monolayers (SAMs) with known heli

Atomic-Scale Origin of Long-Term Stability and High Performance of p-GaN Nanowire Arrays for Photocatalytic Overall Pure Water Splitting

Autor: Zetian Mi, Golam Kibria, F. J. Himpsel, Wanli Yang, Idris Boukahil, Michel L. Trudeau, Xianghua Kong, Ruimin Qiao, Hong Guo, Faqrul A. Chowdhury, Wei Ji, Lionel Vayssieres

Publikováno v: Advanced materials (Deerfield Beach, Fla.). 28(38)

The atomic-scale origin of the unusually high performance and long-term stability of wurtzite p-GaN oriented nanowire arrays is revealed. Nitrogen termination of both the polar (0001¯) top face and the nonpolar (101¯0) side faces of the nanowires i

X-ray absorption spectroscopy (XAS) is combined with density functional theory (DFT) to determine the orbitals of one- and two-dimensional carbon π-systems (lycopene, beta-carotene, retinal, retinol, retinoic acid, coronene, triphenylene). Considera

High Hole Mobility and Thickness-Dependent Crystal Structure in α,ω-Dihexylsexithiophene Single-Monolayer Field-Effect Transistors

Autor: Z. Cai, Mannebach Ehren, Paul G. Evans, Phillip S. Johnson, Josef W. Spalenka, F. J. Himpsel

Publikováno v: Advanced Functional Materials. 23:554-564

Monolayer-thickness two-dimensional layers of α,ω-dihexylsexithiophene (α,ω-DH6T) exhibit field-effect hole mobility of up to 0.032 cm2 V−1 s−1, higher than previously reported for monolayers of other small-molecule organic semiconductors. In

Photon-in photon-out soft X-ray spectroscopy for materials science

Autor: F. J. Himpsel

Publikováno v: physica status solidi (b). 248:292-298

A brief overview of the three elements of photon-in photon-out spectroscopy is given, i.e., X-ray absorption spectroscopy (XAS), X-ray emission spectroscopy (XES), and resonant inelastic X-ray scattering (RIXS). Key features are emphasized, such as e

Angle-resolved photoemission: From reciprocal space to real space

Autor: F. J. Himpsel

Publikováno v: Journal of Electron Spectroscopy and Related Phenomena. 183:114-117

The prospects for converting angle-resolved photoemission data from reciprocal space to real space are evaluated. Examples are given for one- and two-dimensional systems, where wave functions have been obtained for quantum well states confined betwee
