Origin of optical anisotropy in reflectance anisotropy spectroscopy of semiconductor surfaces

SPIE Proceedings, 2006
The 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

Real-time reflectance anisotropy spectroscopy of GaAs homoepitaxy

Applied Optics, 2020
Reflectance anisotropy spectroscopy (RAS) is a highly sensitive optical probe for the real-time study of the epitaxial growth of zincblende semiconductors. Here we report on (1) non-equilibrium RAS spectra acquired in real time during the homoepitaxial growth of GaAs, and (2) RAS spectra for GaAs surfaces under equilibrium with several arsenic ...

Reflection anisotropy spectroscopy

Reports on Progress in Physics, 2005
Reflection anisotropy spectroscopy (RAS) is a non-destructive optical probe of surfaces that is capable of operation within a wide range of environments. In this review we trace the development of RAS from its origins in the 1980s as a probe of semiconductor surfaces and semiconductor growth through to the present where it is emerging as a powerful ...

DIFFERENTIAL-REFLECTANCE SPECTROSCOPY AND REFLECTANCE-ANISOTROPY SPECTROSCOPY ON SEMICONDUCTOR SURFACES

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.

Azimuth-dependent reflection anisotropy spectroscopy

Journal of Applied Physics, 2003
A 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

Separation of optical anisotropies by angular dependent reflection anisotropy spectroscopy

Applied Physics Letters, 2002
Double 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 ...

The optical anisotropy of Pt(100) studied by reflection anisotropy spectroscopy

Physica Status Solidi (a), 1995
The 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 ...

Reflection anisotropy spectroscopy of the oxidized diamond (001) surface

Journal of Physics: Condensed Matter, 2009
We report reflection anisotropy spectroscopy (RAS) measurements of the oxidized (001) surface of a type IIb natural diamond. These measurements were made possible due to recent developments in diamond surface preparation. We compare RAS results from the hydrogenated, clean and oxidized C(001) surface and demonstrate that RAS is sensitive to the ...
