Surface Review and Letters, 1999
The development and the state of the art of surface methods based on the reflection of light are briefly reviewed. A short account is given of the main experimental and theoretical results obtained on semiconductor surfaces over about three decades.

Anisotropy anomalies of the reflectivity of Se
Solid State Communications, 1982Abstract The reflectivity of trigonal Se based on the self-consistent Hartree-Fock-Slater calculation and the rigorous treatment of the matrix elements is presented for 0–25 eV. Close agreement with the experimental reflectivities is found. The peaks are interpreted in terms of the band triplets.

High Angular Resolution Measurements of the Anisotropy of Reflectance of Sea Ice and Snow
Earth and Space Science, 2018 ©2018. American Geophysical Union. We introduce a new method to determine the anisotropy of reflectance of sea ice and snow at spatial scales from 1 m 2 to 80 m 2 using a multispectral circular fish-eye radiance camera (CE600). The CE600 allows measuring

Reflectance anisotropy of the (110) reconstructed surface of gold
Physical Review B, 1990Les calculs d'anisotropie utilisent une theorie perturbative des champs electromagnetiques pres de l'interface microrugueuse. La dispersion spatiale est prise en compte en appliquant une extension de la methode de Rayleigh aux systemes rugueux non locaux.

Separation of optical anisotropies by angular dependent reflection anisotropy spectroscopy
Applied Physics Letters, 2002Double rubbing of polymer films, which finds applications in modern liquid crystal devices, has been investigated using reflection anisotropy spectroscopy (RAS) and atomic force microscopy. A method of gauging the relative strength of rubbing in two different directions, based upon the dependence of observed RAS signals on the sample azimuthal angle ...

Data reduction for spatially resolved reflectance anisotropy spectrometer
Review of Scientific Instruments, 2023We show that in spatially resolved reflectance anisotropy (RA) spectrometers, off-axis optical rays introduce a spurious signal component that cannot be addressed by optical alignment. Such a component is associated with the difference between the reflectivities s and p of the sample and depends, in a complex manner, on the incidence position of the ...

Origin of optical anisotropy in reflectance anisotropy spectroscopy of semiconductor surfaces
SPIE Proceedings, 2006The optical anisotropy of a semiconductor surface can have different origins, such as, local-field effects, the electro-optics effect, reconstruction, surface dislocations, and surface roughness. A comprehensive, quantitative picture on how these effects are related to surface optical anisotropies (SOA) can now be obtained thanks to the progress in the

The optical anisotropy of Pt(100) studied by reflection anisotropy spectroscopy
Physica Status Solidi (a), 1995The optical anisotropy of the Pt(100) hex-R0.7° reconstructed phase is studied with reflection anisotropy spectroscopy. The transition from the hex-R0.7° to the Pt(1 x 1) structure is also studied. The spectrum of Pt(100) hex-R0.7° is found to be dominated by surface polariton-like absorption due to the wavy nature of the first layer superstructure ...

The application of Reflectance Anisotropy Spectroscopy to organics deposition
EPIOPTICS-7, 2004We present the use of Reflectance Anisotropy Spectroscopy (RAS) as a probe to study the deposition of organics We started the study of ordered layers deposited onto disordered substrates by Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) techniques, nevertheless we believe that the goal is the application of RAS to OMBE (Organic Molecular Beam ...

Azimuth-dependent reflection anisotropy spectroscopy
Journal of Applied Physics, 2003A detailed explanation of “azimuth dependent reflection anisotropy spectroscopy” (ADRAS) [B. F. Macdonald and R. J. Cole, Appl. Phys. Lett. 80, 3527 (2002)] is presented. Experimental data and simulations are used to illustrate the greater information content of ADRAS compared to the standard reflection anisotropy technique. The application of ADRAS to
